Got those same routines right here in FreeBSD. Be sure to include the
following in your kernel configuration if you want them to work:
options SYSVSHM
options SYSVSEM
options SYSVMSG
Technically, you only need the first and the last, but why not get
semaphores while you're at it?
Has anyone out there ever wrapped a class around these so they're a
little more usable? The SYSV IPC mechanisms are pretty powerful, but
the semaphores and message queues have an *awful* interface.
Hmmm... a nice little weekend (or two) project in C++ class
construction. Any takers? (I.e. I don't want to do it myself; call
me lazy.)
