The message queue must be designed to be efficient and use as little memory as possible. The only support provided is for a point-to-point message queue.
If there are several readers, each reader can read only the current message at the head of the queue when a read request is made. The CreateMsgQueue function enables the specification of a remote queue.
In addition to the buffer allocated to store messages, a special single-message buffer is used to store a high-priority message or alert message.
