Non blocking socket send

[yaron]

Hi all,

under heavy load i get a SocketException when calling socket.Send method on
non blocking socket with error code 10035 WSAEWOULDBLOCK.

my question is , how do i know the number of bytes that was successfully
send (though there was an exception) so i will not have to send the whole
buffer again ?

Thanks.

It is a nonfatal error, and the operation should be retried later. It is normal for WSAEWOULDBLOCK to be reported as the result from calling connect on a nonblocking SOCK_STREAM socket, since some time must elapse for the connection to be established.
