Can a blocking connect() return successfully if the server application has not issued an accept()? It seems once the server calls listen() this is the case. Is the inbound connection(s) then queued up by the OS waiting for the application to accept()?
I believe the answer to your question is 'no'. I may be off on this, but 'listen' can que up to SOMAXCON (I think that's the name), which is defined as 5, incoming connections. That is to say, it'll hold them until accept is called. I'm not an expert in this, but that is my understanding of it. As such, I doubt that 'connect' will return true there.
Try it and find out. Write a small client and server, and never have the server 'accept'.
Quzah.
Hope is the first step on the road to disappointment.
