+.B getgid()

+.B getegid()
+.SH DESCRIPTION
+.I Getuid
+returns the real user ID of the current process,
+.I geteuid
+the effective user ID.
+The real user ID identifies the person who is logged in,
+in contradistinction to the effective user ID, which
+determines his access permission at the moment.
+It is thus useful to programs which operate using
+the `set user ID' mode, to find out who invoked them.
+.PP
+.I Getgid
+returns the real group ID,
+.I getegid
+the effective group ID.
