[Libsysio-commit] HEAD: libsysio/src rw.c

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

Update of /cvsroot/libsysio/libsysio/src
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv13890/src

Modified Files:
	rw.c 
Log Message:


From Kevin Pedretti: Various rw routines returned a negated errno on errors.
The _sysio_sum_iovec returns a count or negated errno. The internal helper
routines were inverting this on error but indicating error themselves. The
public interface routines would then invert the error number again before
setting errno. The result; -1 * -1 * -n.

Changed the helper routines to pass the error number untouched.
