[Beepcore-c-users] threading: is lock needed in pro_message_available

[Lei Z. <lz...@ju...>]

Howdy,

I've been digging the wrapper code to no avail for answer to a simple 
question: it seems each incoming message gets delivered to the 
application via a different thread, should I use lock to protect 
critical section in pro_message_available?  Some testing shows that the 
application gets notified about an incoming message only after it has 
finished sending RPY to the previous message - is this observation wrong?

Any hint is immensely appreciated.
