+POSIX Message Queues
+CONFIG_OC_PMQUEUE
+  The message passing facility described in IEEE Std 1003.1-2001 allows 
+  processes and threads to communicate through system-wide queues. These 
+  message queues are accessed through names. A message queue can be 
+  opened for use by multiple sending and/or multiple receiving processes.
+
+  Interprocess communication utilizing message passing is a key facility 
+  for the construction of deterministic, high-performance realtime 
+  applications.
+
+  Some characteristics of POSIX Message Queues are:
+       - Fixed size of messages
+       - Prioritization of messages
+       - Asynchronous notification
