An upcoming project requires some efficient interprocess communications
to be developed using XENIX 386's V2.3.1
Since my working knowledge of IPC's is a small subset of total ignorance,
I could really use (and appreciate) code fragments incorporating any of
the following:
msgctl(S) msgget(S) msgop(S)
semctl(S) semget(S) semop(S)
shmctl(S) shmget(S) shmop(S)
ipcs(C) ipcrm(C)
Exercises and "just-playing-around-with" type code would be wonderfull.
Formally correct code would be ideal.
Dont be shy about "sloppy" code though, its just between You and Me, and
I'll rework anything I receive to suit my own twisted idea of apropos'
If there is interest in this project i'll be happy to post a set of
commented exercises using some or all of these functions as a result
of my learning process.

This includes full listings of test programs that exercise all aspects of the IPC system calls. I haven't tried them, but they look pretty good. I think you'll find them a great help.

(This is generic UNIX stuff - generic, at least, to systems that have picked up S5 IPC - so we move it here to "comp.unix.questions"....) >The "AT&T UNIX System V/386 Programmer's Guide" has a whole chapter on >IPCs.

Yes, but it's derived from UNIX, and I'd expect that whoever put S5 IPC into it probably used as much of AT&T's code as possible. The vendors of XENIX System V may even claim SVID compliance for that part of the system....

I suggest you read the book "Advanced UNIX Programming" by Marc J. Rochkind. It explains IPC very good, and contains some sample programs which utilises shared memory, semaphores and message queues. -- Steinar Overbeck Cook, Fellesdata a.s, P.O.
