SYNTAX

       #include <fd.h>

       int fd_copy(to,from);

       int to;
       int from;

DESCRIPTION

       fd_copy  copies  descriptor  from  to descriptor to.  If to was already
       open, fd_copy closes it.  fd_copy always leaves from intact; if to  and
       from are the same number, fd_copy does nothing.

       fd_copy  returns 0 on success, -1 on error.  fd_copy does not guarantee
       that to will remain open, if it was open, in case of error.
