NAME    [Toc]    [Back]

     getgid, getegid - get group process identification

SYNOPSIS    [Toc]    [Back]

     #include <sys/types.h>
     #include <unistd.h>

     gid_t
     getgid(void);

     gid_t
     getegid(void);

DESCRIPTION    [Toc]    [Back]

     The getgid() function returns the real group ID of the calling process,
     getegid() returns the effective group ID of the calling process.

     The real group ID is specified at login time.

     The real group ID is the group of the user who  invoked  the
program.  As
     the  effective group ID gives the process additional permissions during
     the execution of ``set-group-ID'' mode  processes,  getgid()
is used to determine
 the real group ID of the calling process.

ERRORS    [Toc]    [Back]

     The  getgid() and getegid() functions are always successful,
and no return
     value is reserved to indicate an error.
