question on pthreads

[Irfan Habib]

Hi,

Where should I look for the code of the native Pthreads implemetation:

I've found this:
http://pauillac.inria.fr/~xleroy/linuxthreads/

Supposedly from the site,it has been superceeded by NPTL by Ulrich
Drepper, but I cant find the code for NPTL?

It is in glibc.

pthreads (whitch is now NPTL), is part of glibc and can be found at
http://www.gnu.org/software/libc/

You can find nice manual here, and overview
http://www.gnu.org/software/libc/manual/html_mono/libc.html

Also keep in mind that soem distros, patch their glibs, so you might want
to get sources from there

have a nice day,

Unfortunately the NPTL documentation is FAR from complete - there are no
man pages at all, and some featured are completely undocumented.  For
example process-shared mutexes are supported, but the only way you'd
know is to look at the source.  The only docs I could find on how to use
them were old Solaris man pages.

glibc 2.4.31 has a man page for it.

That's not in glibc, that's in the POSIX part of the manpages
distribution.

True but non of my machines had that manpage until the support was in glibc.
Coincidence? Could be I guess...
