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 provide the following wrappers to STDC functions:
58 * To register hooks which are executed on exit().
59 * Usually a wrapper for STDC atexit.
