Implementing sendmsg()/recvmsg() methods on Windows

[artiomn]

Feature or enhancement

Proposal:

Methods socket.sendmsg() and socket.recvmsg() are implemented only for Unix-like systems.
But Windows OS has similar API too: https://learn.microsoft.com/en-us/windows/win32/api/winsock2/nf-winsock2-wsasendmsg

Implementing these methods for WinSock2 will improve Python code portability.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

This actually has been discussed previously -- #50809 (comment)

I don't know if it's feasible to support these new APIs at the socket module level on Windows, but any patches along those lines should also be placed in a new issue rather than being added to this one.
