GETGID(2)           UNIX Programmer's Manual            GETGID(2)



NAME
     getgid, getegid - get group identity

SYNOPSIS
     #include <sys/types.h>

     gid = getgid()
     gid_t gid;

     egid = getegid()
     gid_t egid;

DESCRIPTION
     _G_e_t_g_i_d returns the real group ID of the current process,
     _g_e_t_e_g_i_d 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 _g_e_t_g_i_d
     is most useful.
