GETGID(2)               COMMAND REFERENCE               GETGID(2)



NAME
     getgid, getegid - get group identity

SYNOPSIS
     gid = getgid()
     int gid;

     egid = getegid() int egid;

DESCRIPTION
     Getgid returns the real group ID of the current process in
     gid. Getegid returns the effective group ID in egid. A user
     may be a member of up to eight groups, as discussed in
     getgroups(2).

     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.  It is for such processes that getgid is
     most useful.

RETURN VALUE
     Getgid returns the real group ID of the current process in
     gid. Getegid returns the effective group ID in egid.

SEE ALSO
     getgroups(2), getuid(2), setregid(2), and setgid(3c).
