[gnome-db] New Proporsol Functions for 2.7 developmen series

[Daniel Espinosa <esodan gmail com>]

I'm working in port the current implementation of GdaValue (from the
www.gnome-db.org proyect), to use as the container of values the
GValue of GLib.

But I find that GdaValue requires some king of data types, that must
need derived from a G_TYPE_CHAR/UCHAR and G_TYPE_INT/UINT fundamental
types; then hard code a function to derive a type from the existing
one, and create the g_value_get/set respective functions.

Then I suggest to add the followin functions to the GLib, to give to
the developer the necesary functions to do so.

The functions are:

GType
g_char_type_register_static (const gchar *name)
{
  static const GTypeInfo type_info = {
    0,			/* class_size */
    NULL,		/* base_init */
    NULL,		/* base_finalize */
    NULL,		/* class_init */
    NULL,		/* class_finalize */
    NULL,		/* class_data */
    0,			/* instance_size */
    0,			/* n_preallocs */
    NULL,		/* instance_init */
    NULL		/* value_table */
  };
  GType type;

  g_return_val_if_fail (name != NULL, 0);
  g_return_val_if_fail (g_type_from_name (name) == 0, 0);

  type = g_type_register_static (G_TYPE_CHAR, name, &type_info, 0);

  return type;
}


GType
g_uchar_type_register_static (const gchar *name)
{
  static const GTypeInfo type_info = {
    0,			/* class_size */
    NULL,		/* base_init */
    NULL,		/* base_finalize */
    NULL,		/* class_init */
    NULL,		/* class_finalize */
    NULL,		/* class_data */
    0,			/* instance_size */
    0,			/* n_preallocs */
    NULL,		/* instance_init */
    NULL		/* value_table */
  };
  GType type;

  g_return_val_if_fail (name != NULL, 0);
  g_return_val_if_fail (g_type_from_name (name) == 0, 0);

  type = g_type_register_static (G_TYPE_UCHAR, name, &type_info, 0);
