Hi,
Harring Figueiredo suggested:
Shouldn't the tests be if(buffer_... = NULL)? Probably a typo
You agreed.
In fact, shouldn't it be if(buffer_... == NULL)? (Comparison, not assignment).
Regards
Chris

Chris, Harring had actually written it the right way; the problem is that our Mailbag editor was still getting used to processing the content, and managed to scrog that whole exchange. If you take a look at the original article (http://linuxgazette.net/129/appaiah.html), you'll see that the correction I made to the text uses a '==', not a '='.
(I don't think my fingers would have let me type 'if (x = y)' in
anything but a citation of wrong code; I've done a lot of programming
and teaching over the years, and am allergic to testing the '=' operator
for success or failure.
