> I'd appreciate "even more so" over of "not exactly", as this confirms the point: Unix programming means to use the C library, even plus a bit (superset). Your claim is wrong, on a factual level. "The posix programming interface" is not "the C library". So no, not "even more so". > Unix programming means to use the C library, even plus a bit This was not what you claimed, and it is entirely possible to write a C program that only uses the POSIX specific functions and avoids any of the functions in the C standard library. It won't do much, but it will run to completion.
