27 * G_MINLONG, G_MAXLONG
28 * G_MINFLOAT, G_MAXFLOAT
29 * G_MINDOUBLE, G_MAXDOUBLE
31 * It also provides the following typedefs:
38 * It defines the G_BYTE_ORDER symbol to one of G_*_ENDIAN (see later in
41 * And it provides a way to store and retrieve a `gint' in/from a `gpointer'.
42 * This is useful to pass an integer instead of a pointer to a callback.
44 * GINT_TO_POINTER(i), GUINT_TO_POINTER(i)
45 * GPOINTER_TO_INT(p), GPOINTER_TO_UINT(p)
