I've been working on a C/C++ Source Code search website for over
a year now, and just thought I'd let you all know that I just put it
live a few minutes ago.
It searches 99 million lines of C/C++ code and allows you to choose
exactly what to search for (classes, function names, comments, called
functions, structs, unions, etc.)
Anyways, I hope some people fine it useful, you can find it at:http://csourcesearch.net/
Oh, and it's just one little server, so it might be all that fast,
sorry, but it's all I can afford.
