I appologize, I was reading something, and what I found in the GCC standard headers, and a couple of test outputs, didn't quite fit with what I was reading on networked/IO things, and therefore, I concluded there was something specific to the GCC implementation, and hence this list seemed the most appropriate. Also, a Unix mailing list would be less appropriate, as this isn't Unix specific. Assuming my question weren't related to GCCs implementation of this part of the C networking library, I'd want a networking/IO based mailing list. -Jim Stapleton
