+ *  _CORE_message_queue_Broadcast
+ *
+ *  This function sends a message for every thread waiting on the queue and
+ *  returns the number of threads made ready by the message.
+ *
+ *  Input parameters:
+ *    the_message_queue            - message is submitted to this message queue
+ *    buffer                       - pointer to message buffer
+ *    size                         - size in bytes of message to send
+ *    id                           - id of message queue
+ *    api_message_queue_mp_support - api specific mp support callout
+ *    count                        - area to store number of threads made ready
+ *
+ *  Output parameters:
+ *    count                         - number of threads made ready
+ *    CORE_MESSAGE_QUEUE_SUCCESSFUL - if successful
+ *    error code                    - if unsuccessful
