See page https://learn.microsoft.com/en-us/windows/win32/winsock/winsock-ecn.
I tried to find sendmsg and recvmsg functions, but couldn't find them. In which header are they defined? Or are these wrapper functions I have to write myself?

    Hi, @Koen De Schepper

    They've already been defined by LPFN_WSARECVMSG and LPFN_WSASENDMSG in parametric functions: void sendEcn and recvEcn. LPFN_WSARECVMSG and LPFN_WSASENDMSG are function pointer type. You shall see the doc: https://learn.microsoft.com/en-us/windows/win32/api/mswsock/nc-mswsock-lpfn_wsarecvmsg

    But it seems the doc of LPFN_WSASENDMSG is missing. I'll checked and report it.

    I'm sure it can run well. It has an official sample: https://github.com/microsoft/Windows-classic-samples/blob/main/Samples/Win7Samples/netds/winsock/sendmsg/SendMsg.cpp

    recvand send
