SYNOPSIS    [Toc]    [Back]

     #include <sys/types.h>

     int
     setruid(uid_t uid);

DESCRIPTION    [Toc]    [Back]

     This interface is  made  obsolete  by  setreuid(2).   It  is
available from the
     compatibility library, libcompat.

     The  setruid()  function  (setrgid())  sets the real user ID
(group ID) of
     the current process to the specified value.

RETURN VALUES    [Toc]    [Back]

     Upon success, these functions return 0; otherwise -1 is  returned.

     If  the  user is not the super user, or the UID (GID) specified is not the
     real or effective ID of the process, these functions  return
-1.
