So, the info format documentation shipped in glibc-2.6-4 is old. It says: This is Edition 0.10, last updated 2001-07-06, of `The GNU C Library Reference Manual', for Version 2.3.x of the GNU C Library. And it is incomplete since it doesn't document the pthread_* functions. I've noticed that on http://www.gnu.org/software/libc/manual/ the docs are up-to-date though they don't include pthread either. If pthread is not to be documented there where should I look? The man pages? Are they updated with current glibc developments? Thanks
It is not outdated, that date etc. match what has been last printed by GNU at the time glibc 2.6 has been branched. Since then a newer print has been done and therefore 2007-07-30 Roland McGrath <roland> * manual/libc.texinfo: Update copyrights, formatting magic, and @dircategory. From Karl Berry <karl>. updated it in 2.6.90. That doesn't mean the actual content of the documentation is obsolete, it has updates until EOY 2006. pthread documentation used to be a part of linuxthreads which has been dropped, but AFAIK wasn't copyright owned by FSF and worse was helplessly outdated and described the non-standard conforming LinuxThreads implementation, so it is not really useful for NPTL. NPTL is aiming to be POSIX conformant, so just use POSIX documentation, either in the form of 3p manpages in the distro, or online http://www.opengroup.org/onlinepubs/009695399/nfindex.html
