[Libsysio-commit] HEAD: libsysio/include file.h

[Lee W. <lw...@us...>]

Update of /cvsroot/libsysio/libsysio/include
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv2742/include

Modified Files:
	file.h 
Log Message:


_sysio_fd_dup2 name and usage has changed:

1) New name is _sysio_fd_dup

2) newfd < 0; Same behavior as before.

3) newfd >= 0 && force; Same behavior as before (dup2).

4) newfd >= 0 && !force; Find an available
	descriptor >= newfd (see fcntl-DUPFD)


_sysio_set_fd usage has changed. It takes a new `force' flag. See
discussion above (2, 3, and 4) for description.

Fixed a bug in fcntl. The error return logic was wrong.
