I am using Asyncronous sockets for a small proxy application. There are a lot of connections going on through the program and I find the client usually gets disconnected BEFORE all the data is recieved I solve the incoming data problem by testing the input buffer before closing, but I need to check if all the data has been SENT before closing the connetion So basically how do I check the output buffer on a socket? Once I know that I can put it in the WM_WRITE message to close the sockjet once finished
