Depends what you mean by "information"? A grep on the sources turns up these references:

But presumable you (could?) have done that yourself.

If you need more info than you can glean from reading your platform specific header file (dosish.h|unixish.h), then you'll probably need to ask (specific!) questions over on p5p.

Examine what is said, not who speaks.
Silence betokens consent.
Love the truth but pardon error.
