I'm looking for the pthreads standard for some work I'm doing on parallelism. I have found that it is supposed to be IEEE 1003.1c "EEE Standard for Information Technology--Portable Operating System Interface (POSIX(R)) - System Application Program Interface (API) Amendment 2: Threads Extension (C Language)".
However, when I get to it, it says that the standard has been "superseded", but they don't say by what (or I failed to see where they do say it). What is the link to the superseding standard?
It's been superseded by a newer edition (2008). It's available as IEEE 1003.1-2008 or ISO/IEC 9945-2009 (for enough money) or The Open Group Single Unix Specification, version 7 (for free). All three have identical content.
