Description
The XSI extensions of POSIX contains a portable IPC API. To ease porting of Unix applications, it would be beneficial if Haiku supported this extension.

POSIX XSI IPC contains: semaphores, message queue and shared memory.
Semaphores have been implemented, and so message queue (about to commit the last piece). The only one missing is shared memory and we have ticket #2657 for it.
Note:
See TracTickets
for help on using tickets.
Those have a lot of peculiarities, I looked at implementing them through a separate filesystem + library, but there are quite many side-effects on them... Actually it's been long since I've seen something that really required those.
