[Boost-users] [msm] enque vs defer

Hi boost-users/Christophe, Does enqueue and defer use the same underlying queue, and when i defer can i validate my unit testcase to check on the queue size using get_message_queue_size(). I did a quick test on defer and checking the queue size and it didnt work may be there is something wrong in my test program but wanted to check if anyone tried this out. thank you -raj
