POSIX Therads (pthreads) is only a threading architecture, not an RPC
mechanism.
If your code is thread safe (you can do this with the mutexes you mentioned),
it will cope quite comfortably with RPC's.
The implementation of threads on HP-UX swaps runs a thread scheduling thread
as the first non-main thread, and any other thraeds after that have static
stack sizes (these stack sizes can be varied).
As long as data from one thread is not asyncronously munching data from
another thread, you should be fine.
The prefered standard for RPC calls using threads is a standard know as DCE
(Distributed computing Environment). According to the FAQ, DCE is available
for Solaris as an implementation by Transac (also re-sold by Sun). This may
be woth looking into depending on the amount of code already written in your
application.
The DCE FAQ is available at:
ftp.dstc.edu.au in /pub/DCE/FAQ and
http://www.osf.org/dce/faq-mauney.html
Till Next Time....
