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

NAME
       getgid, getegid - get group identity

SYNOPSIS
       #include 
       #include 

       gidt getgid(void);
       gidt getegid(void);

DESCRIPTION
       getgid() returns the real group ID of the calling process.

       getegid() returns the effective group ID of the calling process.

ERRORS
       These functions are always successful.

CONFORMING TO
       POSIX.1-2001, 4.3BSD.

NOTES
       The  original  Linux getgid() and getegid() system calls supported only
       16-bit group IDs.  Subsequently, Linux 2.4 added getgid32()  and  gete‐
       gid32(), supporting 32-bit IDs.  The glibc getgid() and getegid() wrap‐
       per functions transparently deal with the variations across kernel ver‐
       sions.
