Hi,

I would like to write an IOCP server which is act as middle man to receive
the data from client A and pass it to client B

First, when client A and client B connect to the server, i will store both
client socket handles.

First we call WSARecv() with the socket handle from Client A. Server will
able to receive the data from client A.

But after i call WSASend() by using socket handle from Client B in order to
send data from A to B, i able to do it, but after that
GetQueuedCompletionStatus will waiting there for data from Client B.

My question is in order to receive the data from A again, should i call
again WSARecv() after WSASend()?



Hi,

You can use the following APIs to determine the status of one or more
sockets waiting if necessary, just call the API with a timeout & check
the shutdown flag if the timer expires:

select()

WSAAsyncSelect()
