?S:gidtype:
?S:	This variable defines Gid_t to be something like gid_t, int,
?S:	ushort, or whatever type is used to declare the return type
?S:	of getgid().  Typically, it is the type of group ids in the kernel.
?S:.
?C:Gid_t (GIDTYPE):
?C:	This symbol holds the return type of getgid() and the type of
?C:	argument to setrgid() and related functions.  Typically,
?C:	it is the type of group ids in the kernel. It can be int, ushort,
?C:	gid_t, etc... It may be necessary to include <sys/types.h> to get
?C:	any typedef'ed information.
