fd_move(3)

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.
