Winsock error 10043

WSAEPROTONOSUPPORT  -  Protocol not supported.

Basic (Microsoft) information for 10043 a.k.a. WSAEPROTONOSUPPORT

The requested protocol has not been configured into the system, or no implementation for it exists. For example, a socket call requests a SOCK_DGRAM socket, but specifies a stream protocol.

Detailed (Berkeley) information for winsock 10043, described as "Protocol not supported."

Berkeley description: The protocol has not been configured into the system, or no implementation for it exists.

WinSock description: Same as Berkeley. So, for example, if a WinSock implementation doesn't support SOCK_RAW with IPPROTO_IP (or any other protocol), then the call would fail with WSAEPROTONOSUPPORT (however, if it doesn't support SOCK_RAW at all, you should expect WSAESOCKTNOSUPPORT).
