GETGID(2)                     System Calls Manual                    GETGID(2)

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
       access  permission  during execution of a ``set-group-ID'' process, and
       it is for such processes that getgid is most useful.

SEE ALSO
       getuid(2), setgid(2).
