Something like this: #include <glib.h> #include <glib/gstdio.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <gio/gio.h> int ParseVariant (GVariant *value) { GVariant * list; gchar ch1,ch2,ch3;

g_print ("Inside Parse\n");
g_variant_get (value, "((yu)y a(ysb((sss)(sss))))",
&ch1, &x, &ch2, &list); g_variant_iter_init (&iter, list);
while (g_variant_iter_loop (&iter, "(ysb((sss)(sss)))", &ch3, &str1, &bool1, &str2, &str3, &str4, &str5, &str6, &str7)) { g_print ("%s\n", str1); } g_variant_unref(list); } int main() { GVariantBuilder * builder = g_variant_builder_new (G_VARIANT_TYPE ("a(ysb((sss)(sss)))")); g_variant_builder_add (builder, "(ysb((sss)(sss)))", 'J', "Test1", TRUE, "Hn", "di", "hedfs", "dd", "dr", "hdf"); g_variant_builder_add (builder, "(ysb((sss)(sss)))", 'J', "Test2", TRUE, "Hn", "di", "hedfs", "dd", "dr", "hdf");

ParseVariant (result); } From: gtk-list [mailto:gtk-list-bounces gnome org]
On Behalf Of Dhanesh Sudhakaran Nair (RBEI/ECS1) Hi, In my application, i am getting a message over dbus which has to be parsed(extracted) using gvariant functions.
The format string is "((yu)ya(ysb((sss)(sss))))" which is a bit complex one.
Have writen a sample fn to try out the extraction, which is not currently working. //------------------------------------------------------------------------------ #include <glib.h> #include <glib/gstdio.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <gio/gio.h> int ParseVariant (GVariant *value); { GVariantBuilder *devicelist; GVariant *list; GVariant *list_1; gchar ch1,ch2,ch3; gchar *str1,*str2,*str3,*str4,*str5,*str6,*str7 ; gboolean bool1; gint x,y,z; GVariantIter *iter; g_print ("Inside Parse"); // g_print ("g_variant_get_size:%s",g_variant_get_size (&value)); // GVariantIter *iter; g_variant_get (value, "((yu)ya(ysb((sss)(sss))))", &ch1, &x, &ch2, &iter); g_variant_get_type_string (iter); while (g_variant_iter_loop (iter, "ysb((sss)(sss))", &ch3,str1, &bool1, str2, str3, str4, str5, str6, str7)) g_print ("%s\n", str1); g_variant_iter_free (iter); } int main() { GVariantBuilder *builder; GVariant *value; builder = g_variant_builder_new (G_VARIANT_TYPE ("a(ysb((sss)(sss)))")); g_variant_builder_add (builder, "(ysb((sss)(sss)))", 'J', "Test1", TRUE, "Hn", "di", "hedfs", "dd", "dr", "hdf"); g_variant_builder_add (builder, "(ysb((sss)(sss)))", 'J', "Test2", TRUE, "Hn", "di", "hedfs", "dd", "dr", "hdf"); //g_variant_builder_add (builder, "(ysb((sss)(sss)))", 'J', "Test3", TRUE, "Hn", "di", "hedfs", "dd", "dr", "hdf"); GVariant *result = g_variant_new ("((yu)ya(ysb((sss)(sss))))", 'R', 23, 'E', builder); g_variant_builder_unref (builder); ParseVariant (result); } //------------------------------------------------------------------------------ Can anyone help in correcting the parser function (ParseVariant (result)) using which I can extract each element of the variant result.
Thanks in advance. Regards, Dhanesh |
