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.
