Thank you for the confirmation, I have posted my solution approach in users forum, and the documentation was useful for understanding the clear structure.

for the 2nd one, both eventually call \_Submit , and i found that the \_CORE_message_queue_Send() is a extra wrapper defined in coremsgimpl.h which directly calls _Submit without any processing, and Send appending to the end of mq is handled by message_queue_insert() which in turn depends on the submit_type._

please correct me if im wrong.
