   This API allows an OSM to post a message and then be told whether or
   not the system received a successful reply. If the message times out
   then the value '-ETIMEDOUT' is returned. This is a special case. In
   this situation the message may (should) complete at an indefinite time
   in the future. When it completes it will use the memory buffer
   attached to the request. If -ETIMEDOUT is returned then the memory
   buffer must not be freed. Instead the event completion will free them
   for you. In all other cases the buffer are your problem.
   </p><p>

   Returns 0 on success, negative error code on timeout or positive error
   code from reply.
