for dev/test it's more than adequate (or has been so far, at least).

The second is the wonderful GNU pthreads-win32 project
(http://sources.redhat.com/pthreads-win32/), which is very much a serious
effort,
and worth the time of anyone who is trying to develop cross-platform
multi-threaded code.

The purpose of this post is to see what people would think about our using
pthreads-win32 to abstract all (current) platforms to a PTHREADS interface, and
thereby ease the effort of writing the threaded support for the language, and
for
the libraries that explicitly address threading?

Let me know your thoughts.

Cheers

Funny you should bring this up because I was just looking around for this
sort of thing the other day. The "Waitable Objects" thread got me thinking
about the same thing. Plus there's the whole "port Doug Lea's concurrent
library" project.

Anyhow, I didn't get too far in the win32 pthread direction so I made a stab
at a Java-like wait/notify implementation for win32 and linux (attached). A
good solid pthread on win32 might replace the Event code that I'm using
(which was basically suggested by Mike Parker in the Waitable Objects
thread). Once I got some of the concurrent lib working I was thinking of
putting it on dsource.

If this hand-written implementation is too buggy I'd be happy to plug in
some pthread-win32 library.

I have used pthread to port Linux app with MinGW and has problem at
pthread_yield() and with  thread event handling . But if an interface can
abstracted the pthread win32 , it's great . The portable is the best .
