Hi,

How to increase the TCP receive window for a specific socket? - I know how to do so for all the sockets by setting the registry key TcpWindowSize, but how do do that for a specific one?

According to MSFT's documents, the way is

Calling the Windows Sockets function setsockopt, which sets the receive window on a per-socket basis.

But in setsockopt, it is mentioned about SO_RCVBUF :

Specifies the total per-socket buffer space reserved for receives. This is unrelated to SO_MAX_MSG_SIZE and does not necessarily correspond to the size of the TCP receive window.

So is it possible? How?

Thanks.
