From: Bin Meng <[email protected]> Support for the unix socket has existed both in BSD and Linux for the longest time, but not on Windows. Since Windows 10 build 17063 [1], the native support for the unix socket has come to Windows. Starting this build, two Win32 processes can use the AF_UNIX address family over Winsock API to communicate with each other.
