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.
