[comp.os.mach] P-Threads: Info?

georgeb@fai.UUCP (George Bosworth) (02/03/90)

Can any kind person point me to a source of information about
P-threads (yes, P-, not Mach's C-threads), which I understand
are a proposed superset?

Thanks in advance. I'll be glad to post answer(s) that work.

There is a draft proposal (tentatively, 1003.4) working its way through the
IEEE POSIX standardization process, currently entitled "Real Time Extentions
for Portable Operating Systems".  The proposal includes a standardized
application program interface for concurrent, multi-threaded programs, but
there is no commitment to a particular implementation tactic; coroutines,
kernel-supported threads, and "1 process per 'thread'" all seem to be
permissible.  For more information, contact Nawaf Bitar at the Open Software
Foundation (nawaf@osf.org) who, I believe, is Chairman of the responsible
subcommittee.
