-.Dt SETREUID 2
-.Os
-.Sh NAME
-.Nm setreuid
-.Nd set real and effective user ID's
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In unistd.h
-.Ft int
-.Fn setreuid "uid_t ruid" "uid_t euid"
-.Sh DESCRIPTION
-The real and effective user IDs of the
-current process are set according to the arguments.
-If
-.Fa ruid
-or
-.Fa euid
-is -1, the current uid is filled in by the system.
-Unprivileged users may change the real user
-ID to the effective user ID and vice-versa; only the super-user may
-make other changes.
-.Pp
-The
-.Fn setreuid
-function has been used to swap the real and effective user IDs
-in set-user-ID programs to temporarily relinquish the set-user-ID value.
-This purpose is now better served by the use of the
-.Fn seteuid
-function (see
-.Xr setuid 2 ) .
-.Pp
-When setting the real and effective user IDs to the same value,
-the standard
-.Fn setuid
-function is preferred.
-.Sh RETURN VALUES
-.Rv -std setreuid
-.Sh ERRORS
-.Bl -tag -width Er
-.It Bq Er EPERM
-The current process is not the super-user and a change
-other than changing the effective user-id to the real user-id
-was specified.
