Update of /cvsroot/libsysio/libsysio/include
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv1404/include

Modified Files:
	sysio.h 
Log Message:


Ok, round 3 with the _sysio_boot function. Every time I add a new
little option, I'm going to break the Cray crt0 build. New deal, then.

Now, _sysio_boot takes a name and value pair. We call it repeatedly for
different pairs, then. To support legacy, the name/value pairs are:

	"namespace"	and the buffer is the argument
	"cwd"		and the deferred, initial path is the argument

Since it's now 2 calls, I suggest "namespace" first, then "cwd" to
preserve the older behavior.

As previously, _sysio_boot still returns 0 on success or a, negated,
error number. Now, though, you know which failed :-) You decide if it's fatal.

I've also added a new pair identified by "tracing" that enables tracing if
configured for it. The value is a readable string, expected to parse
as a number by strtol. Then, it should turn into a 0 or positive. Zero, being
off and positive being on.
