NAME

       fd_move - renumber a descriptor

SYNTAX

       #include <fd.h>

       int fd_move(to,from);

       int to;
       int from;

DESCRIPTION

       fd_move  moves  descriptor  from to descriptor to.  If to was already open, fd_move closes
       it.  If the move is successful, fd_move closes from.  Exception: if to and  from  are  the
       same number, fd_move does nothing.

       fd_move returns 0 on success, -1 on error.
