Unix domain sockets

[ptrskg]

Hi,

I am looking for an implementation of
"Unix domain sockets" on OpenVMS to speed up local socket communication.

Does anyone know? Own implementation?
Mailboxes?

Thanks
Peter

I know of none. I was looking into this in
regard to GnuPG a few months back. (I later
found that it was less necessary than I had
thought for GnuPG, so I forgot about it.)

The normal "socket.h" does mention AF_UNIX,
but that seems to be the extent of support.

The suggestion I got from a real HP employee
was to use mailboxes, but that sounded to me
like real work. It might pay to whip up a
simple performance test, to see if there's
any real speed gain, before diving in to
make what I assume would be fairly extensive
changes to an existing application.

I don't know of one either. If you're going to do something painful like reimplementing your IPC code, you might want to consider global sections or intra-cluster communication services rather than mailboxes if speed is the primary concern.

Adding to Craig's comment, global sections, ENQs and ASTs. OpenVMS provides several ways for process to process coordination and communication.
