NAME
     getuid, geteuid - get user identity

SYNOPSIS
     uid = getuid()
     int uid;

     euid = geteuid()

DESCRIPTION

     uid; geteuid returns the effective user ID in euid.

     The real user ID identifies the person who is logged in.

     permissions during execution of "set-user-ID" mode
     processes, which use getuid to determine the real user ID of
     the process which invoked them.

RETURN VALUE
     Getuid returns the real user ID; geteuid returns the
     effective user ID.
