# 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).
