Unix System V - message queue
Is Linux System V IPC Message Queue thread safe? I have one process, writing to a message queue. Can I have more than one process reading from the message queue.

i dont think SysV is POSIX compliant, unixware,hp-ux,aix,and irix are though, those are derived from SVR3 and 4...but the OP is saying Linux System V and I personally have never heard of that...

Re: Unix System V - message queue
The Posix standard contains some SysV IPC mechanisms as well as multi-threading. So saying anything about the two together only makes sense under Posix.
