File Transfer using Winsock2
|
| |
I'm trying to transfer a large file between two processes (client/ server) with a proxy process (basically used as a router) in the middle. I can set up the winsock connection.

Property handling of WSARecvFrom returns 10054(WSAECONNRESET)?
|
| |
I heard that overlapped I/O'ed WSARecvFrom may return 10054 (WSAECONNRESET) if the prior sending packet to the unreachable host failed and ICMP packet 'host unreachable' is received. If this occurs, what is the best handling of this case? As far as I know, I used this scheme: WSARecvFrom(); if(it returns 10054) retry WSARecvFrom() until it doesn't return... more »
