SETRUID(3)               BSD Library Functions Manual               SETRUID(3)

NAME
     setruid, setrgid -- set user and group ID

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/types.h>

     int
     setruid(uid_t ruid);

     int
     setrgid(gid_t rgid);

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

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

     If the user is not the super user, or the uid specified is not the real
     or effective ID, these functions return -1.

     The use of these calls is not portable.  Their use is discouraged; they
     will be removed in the future.
