The main three differences why I choose POSIX IPC libraries over System V
IPC libraries are:
1) POSIX IPC is a portable standard. Sys5 is not a portable standard.
2) POSIX IPC must be thread-safe. Sys5 doesn't have to be and probably
isn't.
3) Although not neccesarily faster, POSIX IPC tends to be more up to date
and functional.
I don't believe Linux has POSIX MQ yet however the files I sent can
certainly work on Linux.

Subject: pthread, posix msg queues, and unix ipc
Hello all,
I'm working on multiple platforms using pthreads and deciding on
a message transfer mechanism for each platforms internal transfers
- either posix message queues or unix IPC.
Can someone tell me the main differences between Posix Message Queues and
Unix IPC message transfers using msgget(), msgsnd(), msgrcv() ?
Also, does Linux 2.x support posix message queues ? I cant seem to find
mq_open,
mq_send, etc.. on my Linux 2.4 box. Is this a Linux add-on I need to
download off the net?
Thanks,
Phil
