SETRUID(3) OpenBSD Programmer's Manual SETRUID(3)NAME
setruid, setrgid - set user and group ID
SYNOPSIS
#include <sys/types.h>
int
setruid(uid_t uid);
int
setrgid(gid_t gid);
DESCRIPTION
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
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.

The setruid() and setrgid() functions appeared in 4.2BSD. Semantically

original semantics restored, appeared in OpenBSD 3.3.
