This list is for kernel-level development, such as device drivers, file system plug-ins, NKEs, and so on. Your question is about user space programming, that is, using the standard UNIX APIs. The folks on this list aren't really your best for answering your questions. You may be better off on the darwin-development mailing list. <http://www.lists.apple.com/mailman/listinfo/darwin-development> Beyond that, I highly recommend the book "Advanced Programming in the UNIX Enivronment", by Stevens,, which covers these sorts of topics in great detail.
