Full details of Winsock TCP error 10041 - WSAEPROTOTYPE:

Berkeley description: A protocol was specified that does not support the semantics of the socket type requested. For example, you cannot use the ARPA Internet UDP protocol with type SOCK_STREAM.

WinSock description: Same as Berkeley. This error occurs if you specifically reference a protocol that isn't part of the address family you also reference. The only function that takes these two explicit parameters is.

Developer suggestions: Since there're only one corresponding protocol for each of the datagram and datastream socket types in the Internet address family, you should simply leave the value in the protocol input parameter to. Alternately, you could call or to get the appropriate protocol value from the network system.
