+ * <literal>sftp://foo/file.avi</literal>, then
+ * <literal>/home/user/.gvfs/sftp on foo/file.avi</literal> will be
+ * passed. This will only work if a set of suitable GIO extensions
+ * (such as gvfs 2.26 compiled with FUSE support), is available and
+ * operational; if this is not the case, the URI will be passed
+ * unmodified to the application. Some URIs, such as
+ * <literal>mailto:</literal>, of course cannot be mapped to a POSIX
+ * path (in gvfs there's no FUSE mount for it); such URIs will be
+ * passed unmodified to the application.
+ * Specifically for gvfs 2.26 and later, the POSIX URI will be mapped
+ * back to the GIO URI in the #GFile constructors (since gvfs
+ * implements the #GVfs extension point). As such, if the application
+ * needs to examine the URI, it needs to use g_file_get_uri() or
+ * similar on #GFile. In other words, an application cannot assume
+ * that the URI passed to e.g. g_file_new_for_commandline_arg() is
+ * equal to the result of g_file_get_uri(). The following snippet
+ * illustrates this:
+ * <programlisting>
+ * GFile *f;
+ * char *uri;
+ * file = g_file_new_for_commandline_arg (uri_from_commandline);
+ * uri = g_file_get_uri (file);
+ * strcmp (uri, uri_from_commandline) == 0; // FALSE
+ * g_free (uri);
+ * if (g_file_has_uri_scheme (file, "cdda"))
+ * {
+ * // do something special with uri
+ * }
+ * g_object_unref (file);
+ * </programlisting>
+ * This code will work when both <literal>cdda://sr0/Track
+ * 1.wav</literal> and <literal>/home/user/.gvfs/cdda on sr0/Track
+ * 1.wav</literal> is passed to the application. It should be noted
+ * that it's generally not safe for applications to rely on the format
+ * of a particular URIs. Different launcher applications (e.g. file
+ * managers) may have different ideas of what a given URI means.

+ * @short_description: Asynchronous Function Results
+ * @include: gio/gio.h
+ * @see_also: #GSimpleAsyncResult
+ *
+ * Provides a base class for implementing asynchronous function results.
+ * Asynchronous operations are broken up into two separate operations
+ * which are chained together by a #GAsyncReadyCallback. To begin
+ * an asynchronous operation, provide a #GAsyncReadyCallback to the
+ * asynchronous function. This callback will be triggered when the
+ * operation has completed, and will be passed a #GAsyncResult instance
+ * filled with the details of the operation's success or failure, the
+ * object the asynchronous function was started for and any error codes
+ * returned. The asynchronous callback function is then expected to call
+ * the corresponding "_finish()" function, passing the object the
+ * function was called for, the #GAsyncResult instance, and (optionally)
+ * an @error to grab any error conditions that may have occurred.
+ * The "_finish()" function for an operation takes the generic result
+ * (of type #GAsyncResult) and returns the specific result that the
+ * operation in question yields (e.g. a #GFileEnumerator for a
+ * "enumerate children" operation). If the result or error status of the
+ * operation is not needed, there is no need to call the "_finish()"
+ * function; GIO will take care of cleaning up the result and error
+ * information after the #GAsyncReadyCallback returns. Applications may
+ * also take a reference to the #GAsyncResult and call "_finish()"
+ * later; however, the "_finish()" function may be called at most once.
+ * Example of a typical asynchronous operation flow:
+ * |[
+ * void _theoretical_frobnitz_async (Theoretical *t,
+ * GCancellable *c,
+ * GAsyncReadyCallback *cb,
+ * gpointer u);
+ * gboolean _theoretical_frobnitz_finish (Theoretical *t,
+ * GAsyncResult *res,
+ * GError **e);
+ * static void
+ * frobnitz_result_func (GObject *source_object,
+ * GAsyncResult *res,
+ * gpointer user_data)
+ * {
+ * gboolean success = FALSE;
+ * success = _theoretical_frobnitz_finish (source_object, res, NULL);
+ * if (success)
+ * g_printf ("Hurray!\n");
+ * else
+ * g_printf ("Uh oh!\n");
+ * /<!-- -->* ... *<!-- -->/
+ * }
+ * int main (int argc, void *argv[])

+ * _theoretical_frobnitz_async (theoretical_data,
+ * NULL,
+ * frobnitz_result_func,
+ * NULL);
+ * /<!-- -->* ... *<!-- -->/
+ * }
+ * ]|
+ * The callback for an asynchronous operation is called only once, and is
+ * always called, even in the case of a cancelled operation. On cancellation
+ * the result is a %G_IO_ERROR_CANCELLED error.
+ * Some asynchronous operations are implemented using synchronous calls.
+ * These are run in a separate thread, if #GThread has been initialized, but
+ * otherwise they are sent to the Main Event Loop and processed in an idle
+ * function. So, if you truly need asynchronous operations, make sure to

+ * SECTION:gsimpleasyncresul:
+ * @short_description: Simple asynchronous results implementation
+ * @include: gio/gio.h
+ * @see_also: #GAsyncResult
+ *
+ * Implements #GAsyncResult for simple cases. Most of the time, this
+ * will be all an application needs, and will be used transparently.
+ * Because of this, #GSimpleAsyncResult is used throughout GIO for
+ * handling asynchronous functions.
+ * GSimpleAsyncResult handles #GAsyncReadyCallback<!-- -->s, error
+ * reporting, operation cancellation and the final state of an operation,
+ * completely transparent to the application. Results can be returned
+ * as a pointer e.g. for functions that return data that is collected
+ * asynchronously, a boolean value for checking the success or failure
+ * of an operation, or a #gssize for operations which return the number
+ * of bytes modified by the operation; all of the simple return cases
+ * are covered.
+ * Most of the time, an application will not need to know of the details
+ * of this API; it is handled transparently, and any necessary operations
+ * are handled by #GAsyncResult's interface. However, if implementing a
+ * new GIO module, for writing language bindings, or for complex
+ * applications that need better control of how asynchronous operations
+ * are completed, it is important to understand this functionality.
+ * GSimpleAsyncResults are tagged with the calling function to ensure
+ * that asynchronous functions and their finishing functions are used
+ * together correctly.
+ * To create a new #GSimpleAsyncResult, call g_simple_async_result_new().
+ * If the result needs to be created for a #GError, use
+ * g_simple_async_result_new_from_error(). If a #GError is not available
+ * (e.g. the asynchronous operation's doesn't take a #GError argument),
+ * but the result still needs to be created for an error condition, use
+ * g_simple_async_result_new_error() (or g_simple_async_result_set_error_va()
+ * if your application or binding requires passing a variable argument list
+ * directly), and the error can then be propagated through the use of
+ * g_simple_async_result_propagate_error().
+ * An asynchronous operation can be made to ignore a cancellation event by
+ * calling g_simple_async_result_set_handle_cancellation() with a
+ * #GSimpleAsyncResult for the operation and %FALSE. This is useful for
+ * operations that are dangerous to cancel, such as close (which would
+ * cause a leak if cancelled before being run).
+ * GSimpleAsyncResult can integrate into GLib's event loop, #GMainLoop,
+ * or it can use #GThread<!-- -->s if available.
+ * g_simple_async_result_complete() will finish an I/O task directly
+ * from the point where it is called. g_simple_async_result_complete_in_idle()
+ * will finish it from an idle handler in the <link
+ * linkend="g-main-context-push-thread-default">thread-default main
+ * context</link>. g_simple_async_result_run_in_thread() will run the
+ * job in a separate thread and then deliver the result to the
+ * thread-default main context.
+ * To set the results of an asynchronous function,
+ * g_simple_async_result_set_op_res_gpointer(),
+ * g_simple_async_result_set_op_res_gboolean(), and
+ * g_simple_async_result_set_op_res_gssize()
+ * are provided, setting the operation's result to a gpointer, gboolean, or
+ * gssize, respectively.
+ * Likewise, to get the result of an asynchronous function,
+ * g_simple_async_result_get_op_res_gpointer(),
+ * g_simple_async_result_get_op_res_gboolean(), and
+ * g_simple_async_result_get_op_res_gssize() are
+ * provided, getting the operation's result as a gpointer, gboolean, and
+ * gssize, respectively.
+ * For the details of the requirements implementations must respect, see
+ * #GAsyncResult. A typical implementation of an asynchronous operation
+ * using GSimpleAsyncResult looks something like this:
+ * |[
+ * static void
+ * baked_cb (Cake *cake,
+ * gpointer user_data)
+ * {
+ * /* In this example, this callback is not given a reference to the cake, so
+ * * the GSimpleAsyncResult has to take a reference to it.

+ * "Go to the supermarket");
+ * else
+ * g_simple_async_result_set_op_res_gpointer (result,
+ * g_object_ref (cake),
+ * g_object_unref);
+ * /* In this example, we assume that baked_cb is called as a callback from
+ * * the mainloop, so it's safe to complete the operation synchronously here.
+ * * If, however, _baker_prepare_cake () might call its callback without
+ * * first returning to the mainloop â?? inadvisable, but some APIs do so â??

+/**
+ * GTypeValueTable:
+ * @value_init: Default initialize @values contents by poking values directly into the value->data array. The data array of the #GValue passed into this function was zero-filled with <function>memset()</function>, so no care has to be taken to free any old contents. E.g. for the implementation of a string value that may never be %NULL, the implementation might look like: |[ value->data[0].v_pointer = g_strdup (""); ]|
+ * @value_free: Free any old contents that might be left in the data array of the passed in @value. No resources may remain allocated through the #GValue contents after this function returns. E.g. for our above string type: |[ // only free strings without a specific flag for static storage if (!(value->data[1].v_uint & G_VALUE_NOCOPY_CONTENTS)) g_free (value->data[0].v_pointer); ]|
+ * @value_copy: @dest_value is a #GValue with zero-filled data section and @src_value is a properly setup #GValue of same or derived type. The purpose of this function is to copy the contents of remain valid. String type example: |[ dest_value->data[0].v_pointer = g_strdup (src_value->data[0].v_pointer); ]|
+ * @value_peek_pointer: If the value contents fit into a pointer, such as objects or strings, return this pointer, so the caller can peek at the current contents. To extend on our above string example: |[ return value->data[0].v_pointer; ]|
+ * @collect_format: A string format describing how to collect the contents of this value bit-by-bit. Each character in the format represents an argument to be collected, and the characters themselves indicate the type of the argument. Currently supported arguments are: <variablelist> <varlistentry><term /><listitem><para> 'i' - Integers. passed as collect_values[].v_int. </para></listitem></varlistentry> <varlistentry><term /><listitem><para> 'l' - Longs. passed as collect_values[].v_long. </para></listitem></varlistentry> <varlistentry><term /><listitem><para> 'd' - Doubles. passed as collect_values[].v_double. </para></listitem></varlistentry> <varlistentry><term /><listitem><para> 'p' - Pointers. passed as collect_values[].v_pointer. </para></listitem></varlistentry> </variablelist> It should be noted that for variable argument list construction, ANSI C promotes every type smaller than an integer to an int, and floats to doubles. So for collection of short int or char, 'i
' needs to be used, and for collection of floats 'd'.
+ * @collect_value: The collect_value() function is responsible for converting the values collected from a variable argument list into contents suitable for storage in a GValue. This function should setup does not allow %NULL pointers, it needs to either spew an error, or do an implicit conversion by storing an empty string. The @value passed in to this function has a zero-filled data array, so just like for value_init() it is guaranteed to not contain any old contents that might need freeing. and @collect_values is an array of unions #GTypeCValue with length @n_collect_values, containing the collected values according to @collect_format. It may contain the flag %G_VALUE_NOCOPY_CONTENTS indicating, that the collected value contents may be considered "static" for the duration of the @value lifetime. Thus an extra copy of the contents stored in @collect_values is not required for assignment to @value. For our above string example, we continue with: |[ if (!collect_values[0].v_p
ointer) value->data[0].v_pointer = g_strdup (""); else if (collect_flags & G_VALUE_NOCOPY_CONTENTS) { value->data[0].v_pointer = collect_values[0].v_pointer; // keep a flag for the value_free() implementation to not free this string value->data[1].v_uint = G_VALUE_NOCOPY_CONTENTS; } else value->data[0].v_pointer = g_strdup (collect_values[0].v_pointer); return NULL; ]| It should be noted, that it is generally a bad idea to follow the #G_VALUE_NOCOPY_CONTENTS hint for reference counted types. Due to reentrancy requirements and reference count assertions performed by the #GSignal code, reference counts should always be incremented for reference counted contents stored in the value->data array. To deviate from our string example for a moment, and taking a look at an exemplary implementation for collect_value() of #GObject: |[ if (collect_values[0].v_pointer) { GObject *object = G_OBJECT (collect_values[0].v_pointer); // never honour G_VALUE_NOCOPY_CONTENTS for ref-counted types
value->data[0].v_pointer = g_object_ref (object); return NULL; } else return g_strdup_printf ("Object passed as invalid NULL pointer"); } ]| The reference count for valid objects is always incremented, regardless of @collect_flags. For invalid objects, the example returns a newly allocated string without altering @value. Upon success, collect_value() needs to return %NULL. If, however, an error condition occurred, collect_value() may spew an error by returning a newly allocated non-%NULL string, giving a suitable description of the error condition. The calling code makes no assumptions about the @value contents being valid upon error returns, @value is simply thrown away without further freeing. As such, it is a good idea to not allocate #GValue contents, prior to returning an error, however, collect_values() is not obliged to return a correctly setup @value for error returns, simply because any non-%NULL return is considered a fatal condition so further program behaviour i
s undefined.
+ * @lcopy_format: Format description of the arguments to collect for @lcopy_value, analogous to @collect_format. Usually, @lcopy_format string consists only of 'p's to provide lcopy_value() with pointers to storage locations.
+ * @lcopy_value: This function is responsible for storing the @value contents into arguments passed through a variable argument list which got collected into @collect_values according to @lcopy_format. and @collect_flags may contain %G_VALUE_NOCOPY_CONTENTS. In contrast to collect_value(), lcopy_value() is obliged to always properly support %G_VALUE_NOCOPY_CONTENTS. Similar to collect_value() the function may prematurely abort by returning a newly allocated string describing an error condition. To complete the string example: |[ gchar **string_p = collect_values[0].v_pointer; if (!string_p) return g_strdup_printf ("string location passed as NULL"); if (collect_flags & G_VALUE_NOCOPY_CONTENTS) *string_p = value->data[0].v_pointer; else *string_p = g_strdup (value->data[0].v_pointer); ]| And an illustrative version of lcopy_value() for reference-counted types: |[ GObject **object_p = collect_values[0].v_pointer; if (!object_p) return g_strdup_printf ("object location passed as
NULL"); if (!value->data[0].v_pointer) *object_p = NULL; else if (collect_flags & G_VALUE_NOCOPY_CONTENTS) // always honour *object_p = value->data[0].v_pointer; else *object_p = g_object_ref (value->data[0].v_pointer); return NULL; ]|
+ *
+ * The #GTypeValueTable provides the functions required by the #GValue implementation,
+ * to serve as a container for values of a type.

+ * set a required type.
+ * A module can implement an extension point by specifying the #GType
+ * that implements the functionality. Additionally, each implementation

+ * one by name.
+ * To avoid opening all modules just to find out what extension
+ * points they implement, GIO makes use of a caching mechanism,

+ * Mounting a #GVolume instance is an asynchronous operation. For more
+ * information about asynchronous operations, see #GAsyncReady and
+ * #GSimpleAsyncReady. To mount a #GVolume, first call
+ * g_volume_mount() with (at least) the #GVolume instance, optionally
+ * a #GMountOperation object and a #GAsyncReadyCallback.
+ * Typically, one will only want to pass %NULL for the
+ * #GMountOperation if automounting all volumes when a desktop session
+ * starts since it's not desirable to put up a lot of dialogs asking
+ * for credentials.
+ * The callback will be fired when the operation has resolved (either
+ * with success or failure), and a #GAsyncReady structure will be
+ * passed to the callback. That callback should then call
+ * g_volume_mount_finish() with the #GVolume instance and the

+ * successfully. If an @error is present when g_volume_mount_finish()
+ * is called, then it will be filled with any error information.

+ *
+ * This is the main operation used when converting data. It is to be called
+ * multiple times in a loop, and each time it will do some work, i.e.
+ * producing some output (in @outbuf) or consuming some input (from @inbuf) or
+ * both. If its not possible to do any work an error is returned.
+ * Note that a single call may not consume all input (or any input at all).
+ * Also a call may produce output even if given no input, due to state stored
+ * in the converter producing output.
+ * If any data was either produced or consumed, and then an error happens, then
+ * only the successful conversion is reported and the error is returned on the
+ * next call.
+ * A full conversion loop involves calling this method repeatedly, each time
+ * giving it new input and space output space. When there is no more input
+ * data after the data in @inbuf, the flag %G_CONVERTER_INPUT_AT_END must be set.
+ * The loop will be (unless some error happens) returning %G_CONVERTER_CONVERTED
+ * each time until all data is consumed and all output is produced, then
+ * %G_CONVERTER_FINISHED is returned instead. Note, that %G_CONVERTER_FINISHED
+ * may be returned even if %G_CONVERTER_INPUT_AT_END is not set, for instance
+ * in a decompression converter where the end of data is detectable from the
+ * data (and there might even be other data after the end of the compressed data).
+ * When some data has successfully been converted @bytes_read and is set to
+ * the number of bytes read from @inbuf, and @bytes_written is set to indicate
+ * how many bytes was written to @outbuf. If there are more data to output
+ * or consume (i.e. unless the G_CONVERTER_INPUT_AT_END is specified) then
+ * G_CONVERTER_CONVERTED is returned, and if no more data is to be output
+ * then G_CONVERTER_FINISHED is returned.
+ * On error %G_CONVERTER_ERROR is returned and @error is set accordingly.
+ * Some errors need special handling:
+ * %G_IO_ERROR_NO_SPACE is returned if there is not enough space
+ * to write the resulting converted data, the application should
+ * call the function again with a larger @outbuf to continue.
+ * %G_IO_ERROR_PARTIAL_INPUT is returned if there is not enough
+ * input to fully determine what the conversion should produce,
+ * and the %G_CONVERTER_INPUT_AT_END flag is not set. This happens for
+ * example with an incomplete multibyte sequence when converting text,
+ * or when a regexp matches up to the end of the input (and may match
+ * further input). It may also happen when @inbuf_size is zero and
+ * there is no more data to produce.
+ * When this happens the application should read more input and then
+ * call the function again. If further input shows that there is no
+ * more data call the function again with the same data but with
+ * the %G_CONVERTER_INPUT_AT_END flag set. This may cause the conversion
+ * to finish as e.g. in the regexp match case (or, to fail again with
+ * %G_IO_ERROR_PARTIAL_INPUT in e.g. a charset conversion where the
+ * input is actually partial).
+ * After g_converter_convert() has returned %G_CONVERTER_FINISHED the
+ * converter object is in an invalid state where its not allowed
+ * to call g_converter_convert() anymore. At this time you can only
+ * free the object or call g_converter_reset() to reset it to the
+ * initial state.
+ * If the flag %G_CONVERTER_FLUSH is set then conversion is modified
+ * to try to write out all internal state to the output. The application
+ * has to call the function multiple times with the flag set, and when
+ * the availible input has been consumed and all internal state has
+ * been produced then %G_CONVERTER_FLUSHED (or %G_CONVERTER_FINISHED if
+ * really at the end) is returned instead of %G_CONVERTER_CONVERTED.
+ * This is somewhat similar to what happens at the end of the input stream,
+ * but done in the middle of the data.
+ * This has different meanings for different conversions. For instance
+ * in a compression converter it would mean that we flush all the
+ * compression state into output such that if you uncompress the
+ * compressed data you get back all the input data. Doing this may
+ * make the final file larger due to padding though. Another example
+ * is a regexp conversion, where if you at the end of the flushed data
+ * have a match, but there is also a potential longer match. In the
+ * non-flushed case we would ask for more input, but when flushing we
+ * treat this as the end of input and do the match.
+ * Flushing is not always possible (like if a charset converter flushes
+ * at a partial multibyte sequence). Converters are supposed to try
+ * to produce as much output as possible and then return an error
+ * (typically %G_IO_ERROR_PARTIAL_INPUT).

+ * @G_REGEX_MATCH_NOTBOL: Specifies that first character of the string is not the beginning of a line, so the circumflex metacharacter should not match before it. Setting this without #G_REGEX_MULTILINE (at compile time) causes circumflex never to match. This option affects only the behaviour of the circumflex metacharacter, it does not affect "\A".
+ * @G_REGEX_MATCH_NOTEOL: Specifies that the end of the subject string is not the end of a line, so the dollar metacharacter should not match it nor (except in multiline mode) a newline immediately before it. Setting this without #G_REGEX_MULTILINE (at compile time) causes dollar never to match. This option affects only the behaviour of the dollar metacharacter, it does not affect "\Z" or "\z".
+ * @G_REGEX_MATCH_NOTEMPTY: An empty string is not considered to be a valid match if this option is set. If there are alternatives in the pattern, they are tried. If all the alternatives match the empty string, the entire match fails. For example, if the pattern "a?b?" is applied to a string not beginning with "a" or "b", it matches the empty string at the start of the string. With this flag set, this match is not valid, so GRegex searches further into the string for occurrences of "a" or "b".
+ * @G_REGEX_MATCH_PARTIAL: Turns on the partial matching feature, for more documentation on partial matching see g_match_info_is_partial_match().
+ * @G_REGEX_MATCH_NEWLINE_CR: Overrides the newline definition set when creating a new #GRegex, setting the '\r' character as line terminator.
+ * @G_REGEX_MATCH_NEWLINE_LF: Overrides the newline definition set when creating a new #GRegex, setting the '\n' character as line terminator.

+/**
+ * The string info map is an efficient data structure designed to b:
+ *
+ * used with a small set of items. It is used by GSettings schemas for
+ * three purposes:
+ * 1) Implement <choices> with a list of valid strings
+ * 2) Implement <alias> by mapping one string to another
+ * 3) Implement enumerated types by mapping strings to integer values
+ * (and back).
+ * The map is made out of an array of uint32s. Each entry in the array
+ * is an integer value, followed by a specially formatted string value:
+ * The string starts with the byte 0xff or 0xfe, followed by the
+ * content of the string, followed by a nul byte, followed by
+ * additional nul bytes for padding, followed by a 0xff byte.
+ * Padding is added so that the entire formatted string takes up a
+ * multiple of 4 bytes, and not less than 8 bytes. The requirement
+ * for a string to take up 8 bytes is so that the scanner doesn't lose
+ * synch and mistake a string for an integer value.
+ * The first byte of the formatted string depends on if the integer is
+ * an enum value (0xff) or an alias (0xfe). If it is an alias then the
+ * number refers to the word offset within the info map at which the
+ * integer corresponding to the "target" value is stored.
+ * For example, consider the case of the string info map representing an
+ * enumerated type of 'foo' (value 1) and 'bar' (value 2) and 'baz'
+ * (alias for 'bar'). Note that string info maps are always little
+ * endian.
+ * x01 x00 x00 x00 xff 'f' 'o' 'o' x00 x00 x00 xff x02 x00 x00 x00
+ * xff 'b' 'a' 'r' x00 x00 x00 xff x03 x00 x00 x00 xfe 'b' 'a' 'z'
+ * x00 x00 x00 xff
+ * The operations that someone may want to perform with the map:
+ * - lookup if a string is valid (and not an alias)
+ * - lookup the integer value for a enum 'nick'
+ * - lookup the integer value for the target of an alias
+ * - lookup an alias and convert it to its target string
+ * - lookup the enum nick for a given value
+ * In order to lookup if a string is valid, it is padded on either side
+ * (as described) and scanned for in the array. For example, you might
+ * look for "foo":
+ * xff 'f' 'o' 'o' x00 x00 x00 xff
+ * In order to lookup the integer value for a nick, the string is padded
+ * on either side and scanned for in the array, as above. Instead of
+ * merely succeeding, we look at the integer value to the left of the
+ * match. This is the enum value.
+ * In order to lookup an alias and convert it to its target enum value,
+ * the string is padded on either side (as described, with 0xfe) and
+ * scanned for. For example, you might look for "baz":
+ * xfe 'b' 'a' 'z' x00 x00 x00 xff
+ * The integer immediately preceeding the match then contains the offset
+ * of the integer value of the target. In our example, that's '3'.
+ * This index is dereferenced to find the enum value of '2'.
+ * To convert the alias to its target string, 5 bytes just need to be
+ * added past the start of the integer value to find the start of the
+ * string.
+ * To lookup the enum nick for a given value, the value is searched for
+ * in the array. To ensure that the value isn't matching the inside of a
+ * string, we must check that it is either the first item in the array or
+ * immediately preceeded by the byte 0xff. It must also be immediately
+ * followed by the byte 0xff.
+ * Because strings always take up a minimum of 2 words, because 0xff or
+ * 0xfe never appear inside of a utf-8 string and because no two integer
+ * values ever appear in sequence, the only way we can have the
+ * sequence:
+ * xff __ __ __ __ xff (or 0xfe)
+ * is in the event of an integer nested between two strings.
+ * For implementation simplicity/efficiency, strings may not be more
+ * the value of each choice is set to zero and ignored.
+ *
+ * Than 65 characters in length (ie: 17 32bit words after padding).
+ * In the event that we are doing <choices> (ie: not an enum type) then

+ * The semantics of the interface are very precisely defined and
+ * implementations must carefully adhere to the expectations of

+ * in-process generated errors.
+ * To check if a returned #GError is an error from a remote peer, use

+ * In addition, facilities used to return errors to a remote peer also
+ * use #GError. See g_dbus_method_invocation_return_error() for
+ * discussion about how the D-Bus error name is set.
+ * Applications can associate a #GError error domain with a set of D-Bus errors in order to

+ *
+ * #GDBusProxy is a base class used for proxies to access a D-Bus
+ * interface on a remote object. A #GDBusProxy can be constructed for
+ * both well-known and unique names.
+ * By default, #GDBusProxy will cache all properties (and listen to
+ * changes) of the remote object, and proxy all signals that gets
+ * emitted. This behaviour can be changed by passing suitable
+ * #GDBusProxyFlags when the proxy is created. If the proxy is for a
+ * well-known name, the property cache is flushed when the name owner
+ * vanishes and reloaded when a name owner appears.
+ * If a #GDBusProxy is used for a well-known name, the owner of the
+ * name is tracked and can be read from
+ * #GDBusProxy:g-name-owner. Connect to the #GObject::notify signal to
+ * get notified of changes. Additionally, only signals and property
+ * changes emitted from the current name owner are considered and
+ * calls are always sent to the current name owner. This avoids a
+ * number of race conditions when the name is lost by one owner and
+ * claimed by another. However, if no name owner currently exists,
+ * then calls will be sent to the well-known name which may result in
+ * the message bus launching an owner (unless
+ * %G_DBUS_PROXY_FLAGS_DO_NOT_AUTO_START is set).
+ * The generic #GDBusProxy::g-properties-changed and #GDBusProxy::g-signal
+ * signals are not very convenient to work with. Therefore, the recommended
+ * way of working with proxies is to subclass #GDBusProxy, and have
+ * more natural properties and signals in your derived class.
+ * See <xref linkend="gdbus-example-proxy-subclass"/> for an example.

+ * SECTION:gfil:
+ * @short_description: File and Directory Handling
+ * @include: gio/gio.h
+ * @see_also: #GFileInfo, #GFileEnumerator
+ *
+ * #GFile is a high level abstraction for manipulating files on a
+ * virtual file system. #GFile<!-- -->s are lightweight, immutable
+ * objects that do no I/O upon creation. It is necessary to understand that
+ * #GFile objects do not represent files, merely an identifier for a file. All
+ * file content I/O is implemented as streaming operations (see #GInputStream and
+ * #GOutputStream).
+ * g_file_new_for_path() if you have a path.
+ * g_file_new_for_uri() if you have a URI.
+ * g_file_new_for_commandline_arg() for a command line argument.
+ * g_file_parse_name() from a utf8 string gotten from g_file_get_parse_name().
+ * One way to think of a #GFile is as an abstraction of a pathname. For normal
+ * files the system pathname is what is stored internally, but as #GFile<!-- -->s
+ * are extensible it could also be something else that corresponds to a pathname
+ * in a userspace implementation of a filesystem.
+ * #GFile<!-- -->s make up hierarchies of directories and files that correspond to the
+ * files on a filesystem. You can move through the file system with #GFile using
+ * g_file_get_parent() to get an identifier for the parent directory, g_file_get_child()
+ * to get a child within a directory, g_file_resolve_relative_path() to resolve a relative
+ * path between two #GFile<!-- -->s. There can be multiple hierarchies, so you may not
+ * end up at the same root if you repeatedly call g_file_get_parent() on two different
+ * files.
+ * All #GFile<!-- -->s have a basename (get with g_file_get_basename()). These names
+ * are byte strings that are used to identify the file on the filesystem (relative to
+ * its parent directory) and there is no guarantees that they have any particular charset
+ * encoding or even make any sense at all. If you want to use filenames in a user
+ * interface you should use the display name that you can get by requesting the
+ * %G_FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME attribute with g_file_query_info().
+ * This is guaranteed to be in utf8 and can be used in a user interface. But always
+ * store the real basename or the #GFile to use to actually access the file, because
+ * there is no way to go from a display name to the actual name.
+ * Using #GFile as an identifier has the same weaknesses as using a path in that
+ * there may be multiple aliases for the same file. For instance, hard or
+ * soft links may cause two different #GFile<!-- -->s to refer to the same file.
+ * and long names on Fat/NTFS, or bind mounts in Linux. If you want to check if
+ * two #GFile<!-- -->s point to the same file you can query for the
+ * %G_FILE_ATTRIBUTE_ID_FILE attribute. Note that #GFile does some trivial
+ * canonicalization of pathnames passed in, so that trivial differences in the
+ * path string used at creation (duplicated slashes, slash at end of path, "."
+ * or ".." path segments, etc) does not create different #GFile<!-- -->s.
+ * Many #GFile operations have both synchronous and asynchronous versions
+ * to suit your application. Asynchronous versions of synchronous functions
+ * simply have _async() appended to their function names. The asynchronous
+ * I/O functions call a #GAsyncReadyCallback which is then used to finalize
+ * the operation, producing a GAsyncResult which is then passed to the
+ * function's matching _finish() operation.
+ * Some #GFile operations do not have synchronous analogs, as they may
+ * take a very long time to finish, and blocking may leave an application
+ * unusable. Notable cases include:
+ * g_file_mount_mountable() to mount a mountable file.
+ * g_file_unmount_mountable_with_operation() to unmount a mountable file.
+ * g_file_eject_mountable_with_operation() to eject a mountable file.
+ * <para id="gfile-etag"><indexterm><primary>entity tag</primary></indexterm>
+ * One notable feature of #GFile<!-- -->s are entity tags, or "etags" for
+ * short. Entity tags are somewhat like a more abstract version of the
+ * traditional mtime, and can be used to quickly determine if the file has
+ * been modified from the version on the file system. See the HTTP 1.1
+ * <ulink url="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html";>specification</ulink>
+ * for HTTP Etag headers, which are a very similar concept.
+ * </para>

+ * Other possible causes for aliases are: case insensitive filesystems, short

+ * SECTION:gsocke:
+ * @short_description: Low-level socket object
+ * @include: gio/gio.h
+ * @see_also: #GInitable
+ *
+ * A #GSocket is a low-level networking primitive. It is a more or less
+ * direct mapping of the BSD socket API in a portable GObject based API.
+ * It supports both the UNIX socket implementations and winsock2 on Windows.
+ * #GSocket is the platform independent base upon which the higher level
+ * network primitives are based. Applications are not typically meant to
+ * use it directly, but rather through classes like #GSocketClient,
+ * #GSocketService and #GSocketConnection. However there may be cases where
+ * direct use of #GSocket is useful.
+ * #GSocket implements the #GInitable interface, so if it is manually constructed
+ * by e.g. g_object_new() you must call g_initable_init() and check the
+ * results before using the object. This is done automatically in
+ * g_socket_new() and g_socket_new_from_fd(), so these functions can return
+ * %NULL.
+ * Sockets operate in two general modes, blocking or non-blocking. When
+ * in blocking mode all operations block until the requested operation
+ * is finished or there is an error. In non-blocking mode all calls that
+ * would block return immediately with a %G_IO_ERROR_WOULD_BLOCK error.
+ * To know when a call would successfully run you can call g_socket_condition_check(),
+ * or g_socket_condition_wait(). You can also use g_socket_create_source() and
+ * attach it to a #GMainContext to get callbacks when I/O is possible.
+ * Note that all sockets are always set to non blocking mode in the system, and
+ * blocking mode is emulated in GSocket.
+ * When working in non-blocking mode applications should always be able to
+ * handle getting a %G_IO_ERROR_WOULD_BLOCK error even when some other
+ * function said that I/O was possible. This can easily happen in case
+ * of a race condition in the application, but it can also happen for other
+ * reasons. For instance, on Windows a socket is always seen as writable
+ * until a write returns %G_IO_ERROR_WOULD_BLOCK.
+ * #GSocket<!-- -->s can be either connection oriented or datagram based.
+ * For connection oriented types you must first establish a connection by
+ * either connecting to an address or accepting a connection from another
+ * address. For connectionless socket types the target/source address is
+ * specified or received in each I/O operation.
+ * All socket file descriptors are set to be close-on-exec.
+ * Note that creating a #GSocket causes the signal %SIGPIPE to be
+ * ignored for the remainder of the program. If you are writing a
+ * command-line utility that uses #GSocket, you may need to take into
+ * account the fact that your program will not automatically be killed
+ * if it tries to write to %stdout after it has been closed.

+ * of a specific type. This function should initialize all static class
+ * members.
+ * The initialization process of a class involves:
+ * <itemizedlist>
+ * <listitem><para>
+ * 1 - Copying common members from the parent class over to the
+ * derived class structure.
+ * </para></listitem>

+ * </para></listitem>
+ * <listitem><para>
+ * 4 - Invocation of the class' GClassInitFunc() initializer.
+ * </para></listitem>
+ * </itemizedlist>
+ * Since derived classes are partially initialized through a memory copy
+ * of the parent class, the general rule is that GBaseInitFunc() and
+ * GBaseFinalizeFunc() should take care of necessary reinitialization
+ * and release of those class members that were introduced by the type
+ * that specified these GBaseInitFunc()/GBaseFinalizeFunc().
+ * GClassInitFunc() should only care about initializing static
+ * class members, while dynamic class members (such as allocated strings
+ * or reference counted resources) are better handled by a GBaseInitFunc()
+ * for this type, so proper initialization of the dynamic class members
+ * is performed for class initialization of derived types as well.
+ * An example may help to correspond the intend of the different class
+ * initializers:
+ * |[
+ * typedef struct {
+ * GObjectClass parent_class;
+ * gint static_integer;
+ * gchar *dynamic_string;
+ * } TypeAClass;
+ * static void
+ * type_a_base_class_init (TypeAClass *class)
+ * {
+ * class->dynamic_string = g_strdup ("some string");

+ * }
+ * static void

+ * {
+ * class->static_float = 3.14159265358979323846;
+ * }
+ * ]|
+ * Initialization of TypeBClass will first cause initialization of
+ * TypeAClass (derived classes reference their parent classes, see
+ * g_type_class_ref() on this).
+ * Initialization of TypeAClass roughly involves zero-initializing its fields,
+ * then calling its GBaseInitFunc() type_a_base_class_init() to allocate
+ * its dynamic members (dynamic_string), and finally calling its GClassInitFunc()
+ * type_a_class_init() to initialize its static members (static_integer).
+ * The first step in the initialization process of TypeBClass is then
+ * a plain memory copy of the contents of TypeAClass into TypeBClass and
+ * zero-initialization of the remaining fields in TypeBClass.
+ * The dynamic members of TypeAClass within TypeBClass now need
+ * reinitialization which is performed by calling type_a_base_class_init()
+ * with an argument of TypeBClass.
+ * After that, the GBaseInitFunc() of TypeBClass, type_b_base_class_init()
+ * is called to allocate the dynamic members of TypeBClass (dynamic_gstring),
+ * and finally the GClassInitFunc() of TypeBClass, type_b_class_init(),
+ * is called to complete the initialization process with the static members
+ * (static_float).
+ * Corresponding finalization counter parts to the GBaseInitFunc() functions
+ * have to be provided to release allocated resources at class finalization
+ * time.

+/**
+ * SECTION:gsetting:
+ * @short_description: a high-level API for application settings
+ *
+ * The #GSettings class provides a convenient API for storing and retrieving
+ * application settings.
+ * When creating a GSettings instance, you have to specify a schema
+ * that describes the keys in your settings and their types and default
+ * values, as well as some other information.
+ * Normally, a schema has as fixed path that determines where the settings
+ * are stored in the conceptual global tree of settings. However, schemas
+ * can also be 'relocatable', i.e. not equipped with a fixed path. This is
+ * useful e.g. when the schema describes an 'account', and you want to be
+ * able to store a arbitrary number of accounts.
+ * Unlike other configuration systems (like GConf), GSettings does not
+ * restrict keys to basic types like strings and numbers. GSettings stores
+ * values as #GVariant, and allows any #GVariantType for keys. Key names
+ * are restricted to lowercase characters, numbers and '-'. Furthermore,
+ * the names must begin with a lowercase character, must not end
+ * with a '-', and must not contain consecutive dashes. Key names can
+ * be up to 32 characters long.
+ * Similar to GConf, the default values in GSettings schemas can be
+ * localized, but the localized values are stored in gettext catalogs
+ * and looked up with the domain that is specified in the
+ * <tag class="attribute">gettext-domain</tag> attribute of the
+ * <tag class="starttag">schemalist</tag> or <tag class="starttag">schema</tag>
+ * elements and the category that is specified in the l10n attribute of the
+ * <tag class="starttag">key</tag> element.
+ * GSettings uses schemas in a compact binary form that is created
+ * by the <link linkend="glib-compile-schemas">glib-compile-schemas</link>
+ * utility. The input is a schema description in an XML format that can be
+ * described by the following DTD:
+ * |[<xi:include xmlns:xi="http://www.w3.org/2001/XInclude"; parse="text" href="../../../../gio/gschema.dtd"><xi:fallback>FIXME: MISSING XINCLUDE CONTENT</xi:fallback></xi:include>]|
+ * At runtime, schemas are identified by their id (as specified
+ * in the <tag class="attribute">id</tag> attribute of the
+ * <tag class="starttag">schema</tag> element). The
+ * convention for schema ids is to use a dotted name, similar in
+ * style to a DBus bus name, e.g. "org.gnome.font-rendering".
+ * <example><title>Default values</title>
+ * <programlisting><![CDATA[

+ * <title>Vendor overrides</title>
+ * <para>
+ * Default values are defined in the schemas that get installed by
+ * an application. Sometimes, it is necessary for a vendor or distributor
+ * to adjust these defaults. Since patching the XML source for the schema
+ * is inconvenient and error-prone,
+ * <link linkend="glib-compile-schemas">glib-compile-schemas</link> reads
+ * so-called 'vendor override' files. These are keyfiles in the same
+ * directory as the XML schema sources which can override default values.
+ * The schema id serves as the group name in the key file, and the values
+ * are expected in serialized GVariant form, as in the following example:
+ * <informalexample><programlisting>
+ * [org.gtk.Example]
+ * key1='string'
+ * key2=1.5
+ * </programlisting></informalexample>

+ * <title>Binding</title>
+ * <para>
+ * A very convenient feature of GSettings lets you bind #GObject properties
+ * directly to settings, using g_settings_bind(). Once a GObject property
+ * has been bound to a setting, changes on either side are automatically
+ * propagated to the other side. GSettings handles details like
+ * mapping between GObject and GVariant types, and preventing infinite
+ * cycles.
+ * </para>
+ * <para>
+ * This makes it very easy to hook up a preferences dialog to the
+ * underlying settings. To make this even more convenient, GSettings
+ * looks for a boolean property with the name "sensitivity" and
+ * automatically binds it to the writability of the bound setting.
+ * If this 'magic' gets in the way, it can be suppressed with the
+ * #G_SETTINGS_BIND_NO_SENSITIVITY flag.

+ * @G_REGEX_MULTILINE: By default, GRegex treats the strings as consisting of a single line of characters (even if it actually contains newlines). The "start of line" metacharacter ("^") matches only at the start of the string, while the "end of line" metacharacter ("$") matches only at the end of the string, or before a terminating newline (unless #G_REGEX_DOLLAR_ENDONLY is set). When #G_REGEX_MULTILINE is set, the "start of line" and "end of line" constructs match immediately following or immediately before any newline in the string, respectively, as well as at the very start and end. This can be changed within a pattern by a "(?m)" option setting.
+ * @G_REGEX_DOTALL: A dot metacharater (".") in the pattern matches all characters, including newlines. Without it, newlines are excluded. This option can be changed within a pattern by a ("?s") option setting.
+ * @G_REGEX_EXTENDED: Whitespace data characters in the pattern are totally ignored except when escaped or inside a character class. Whitespace does not include the VT character (code 11). In addition, characters between an unescaped "#" outside a character class and the next newline character, inclusive, are also ignored. This can be changed within a pattern by a "(?x)" option setting.
+ * @G_REGEX_ANCHORED: The pattern is forced to be "anchored", that is, it is constrained to match only at the first matching point in the string that is being searched. This effect can also be achieved by appropriate constructs in the pattern itself such as the "^" metacharater.
+ * @G_REGEX_DOLLAR_ENDONLY: A dollar metacharacter ("$") in the pattern matches only at the end of the string. Without this option, a dollar also matches immediately before the final character if it is a newline (but not before any other newlines). This option is ignored if #G_REGEX_MULTILINE is set.
+ * @G_REGEX_UNGREEDY: Inverts the "greediness" of the quantifiers so that they are not greedy by default, but become greedy if followed by "?". It can also be set by a "(?U)" option setting within the pattern.
+ * @G_REGEX_RAW: Usually strings must be valid UTF-8 strings, using this flag they are considered as a raw sequence of bytes.
+ * @G_REGEX_NO_AUTO_CAPTURE: Disables the use of numbered capturing parentheses in the pattern. Any opening parenthesis that is not followed by "?" behaves as if it were followed by "?:" but named parentheses can still be used for capturing (and they acquire numbers in the usual way).
+ * @G_REGEX_OPTIMIZE: Optimize the regular expression. If the pattern will be used many times, then it may be worth the effort to optimize it to improve the speed of matches.
+ * @G_REGEX_DUPNAMES: Names used to identify capturing subpatterns need not be unique. This can be helpful for certain types of pattern when it is known that only one instance of the named subpattern can ever be matched.
+ * @G_REGEX_NEWLINE_CR: Usually any newline character is recognized, if this option is set, the only recognized newline character is '\r'.
