Obtained WSASendMsg through WSAIoctl, returned 0x80072726

[noah-hwang]

Result =
    WSAIoctl(
        UdpSocket,
        SIO_GET_EXTENSION_FUNCTION_POINTER,
        &WSASendMsgGuid,
        sizeof(WSASendMsgGuid),
        &Datapath->WSASendMsg,
        sizeof(Datapath->WSASendMsg),
        &BytesReturned,
        NULL,
        NULL);
if (Result != NO_ERROR) {
    int WsaError = WSAGetLastError();
    QuicTraceEvent(
        LibraryErrorStatus,
        "[ lib] ERROR, %u, %s.",
        WsaError,
        "SIO_GET_EXTENSION_FUNCTION_POINTER (WSASendMsg)");
    Status = HRESULT_FROM_WIN32(WsaError);
    goto Error;

}
Log as follows:
[ lib] ERROR, 10022, SIO_GET_EXTENSION_FUNCTION_POINTER (WSASendMsg).
Status is 0x80072726: Invalid argument.

This will cause msquic initialization fail.
Is there a way to solve this problem.
Thanks.

Not currently. What version of Windows are you trying to use MsQuic on?

[noah-hwang]

ws2_32.dll version : 10.0.22621.1
windows version : windows10 22H2 19045.5371

How do you have Windows in such a state? Could you explain your scenario more?

[noah-hwang]

An initialization failure occurs when using the msquic client for windows normally, there is no special usage scenario,
and it appears to be an issue only on some windows computers，it's not clear why

The following modification can obtain the pointer, and the connection can be successfully established.

            &BytesReturned,

    if (Result != NO_ERROR) {
        int WsaError = WSAGetLastError();
        QuicTraceEvent(
            LibraryErrorStatus,

            WsaError,
            "SIO_GET_EXTENSION_FUNCTION_POINTER (WSASendMsg)");
        
        HMODULE mHandle = GetModuleHandle("ws2_32.dll");
        if (mHandle == NULL) {
            WsaError = WSAGetLastError();
            QuicTraceEvent(
                LibraryErrorStatus,
                "[ lib] ERROR, %u, %s.",
                WsaError,
                "GetModuleHandle ws2_32.dll");
            Status = HRESULT_FROM_WIN32(WsaError);
            goto Error;
        }
        Datapath->WSASendMsg = (LPFN_WSASENDMSG)GetProcAddress(mHandle, "WSASendMsg");
        if (Datapath->WSASendMsg == NULL) {
            WsaError = WSAGetLastError();
            QuicTraceEvent(
                LibraryErrorStatus,
                "[ lib] ERROR, %u, %s.",
                WsaError,
                "GetProcAddress WSASendMsg null");
            Status = HRESULT_FROM_WIN32(WsaError);
            goto Error;
        }
    }

But this is an unconventional way.
