30 /* system specific config file glibconfig.h provides definitions for
31 * the extrema of many of the standard types. These are:
33 * G_MINSHORT, G_MAXSHORT
35 * G_MINLONG, G_MAXLONG
36 * G_MINFLOAT, G_MAXFLOAT
37 * G_MINDOUBLE, G_MAXDOUBLE
39 * It also provides the following typedefs:
46 * It defines the G_BYTE_ORDER symbol to one of G_*_ENDIAN (see later in
49 * And it provides a way to store and retrieve a `gint' in/from a `gpointer'.
50 * This is useful to pass an integer instead of a pointer to a callback.
52 * GINT_TO_POINTER (i), GUINT_TO_POINTER (i)
53 * GPOINTER_TO_INT (p), GPOINTER_TO_UINT (p)
55 * Finally, it provides the following wrappers to STDC functions:
57 * void g_memmove (gpointer dest, gconstpointer void *src, gulong count);
58 * A wrapper for STDC memmove, or an implementation, if memmove doesn't
59 * exist. The prototype looks like the above, give or take a const,
