GETGID(2)  —  SYSTEM CALLS

NAME

getgid, getegid − get group identity

SYNOPSIS

gid = getgid()
int gid;

egid = getegid()
int egid;

DESCRIPTION

getgid() returns the real group ID of the current process, getegid() the effective group ID. 

The real GID is specified at login time. 

The effective GID is more transient, and determines additional access permission during execution of a “setGID” process, and it is for such processes that getgid() is most useful.
