fd_move3
Renumber a descriptor
Usage
#include <fd.h>
int fd_move(to,from);

Overview
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.
