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.
