[pupnp-user] UpnpSendActionAsync() & UpnpSendAction()

[joshua <jos...@gm...>]

Hi,

My application uses libupnp-1.6.19. I notice that UpnpSendActionAsync() doesn’t guarantee the receiving/executing order. For example,  if action A then B are sent, B may be received and executed first on the other end. 

I read the code a bit, it seems to me that UpnpSendActionAsync() just hands off the request to thread pool, and from there on any order is possible.

Assume I call UpnpSendActionAsync() or UpnpSendAction() in one thread context (same thread).
 my questions are:

1) is that a feature?
2) is there any async api that guarantees A first, then B?
3)  does UpnpSendAction() guarantees  A first, then B?


Thanks,
