Hi,
[Sorry for the delay in responding. I've only just returned from
vacation today.]
The reason Aurelio's message queues aren't in the distribution is
that they rely on PROCESS_SHARED attribute objects, which are not
implemented in pthreads-win32, and therefore they won't work for
IPC. They do work within the same process though, but this is too
limited IMO. If included, I think they would be a trap for
programmers expecting to use them for IPC. See for example:
http://sources.redhat.com/ml/pthreads-win32/2001/msg00101.html
Regards.
Ross
