NAME
getgid, getegid - get group identity
SYNOPSIS
#include <sys/types.h>
#include <unistd.h>
gid_t getgid(void)
gid_t getegid(void)
DESCRIPTION
Getgid returns the real group ID of the current process, getegid the
effective group ID.
The real group ID is specified at login time.
The effective group ID is more transient, and determines additional ac-
cess permission during execution of a ``set-group-ID'' process, and it
is for such processes that getgid is most useful.
