Where is the list of the POSIX C API functions? [closed]

Answer 1

POSIX 1003.1-2008 is now available on the web (all 3872 pages of it, in PDF and HTML). You have to register (free). I got to it from the Open Group Bookstore.

See How to Portably scanf into a pid_t in C for my original answer that included this information.

Answer 2

Strictly speaking, the definitive list of the POSIX functions is the POSIX standards documents themselves.

There's a pretty good introduction to what POSIX is all about, with links to plenty of reference material on Wikipedia.

Answer 3

zipped versions of the HTML for grepping

• http://pubs.opengroup.org/onlinepubs/9699919799/download/
• http://pubs.opengroup.org/onlinepubs/9699919799/download/susv4tc2.zip

Those are useful when you start wanting to grep for things, without paying for the PDF.
