Well yes, the *_r functions are often pretty ugly to use. But they work great if what you want to do is build your own thread local storage version on top! I've always assumed there's some good reason for the existence and use of *_r functions rather than equivalent thread local storage versions, although I've never been sure just what it is. -- Andrew Piskorski <[EMAIL PROTECTED]> http://www.piskorski.com/
