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.
[1] https://devblogs.microsoft.com/commandline/af_unix-comes-to-windows/ Changes in v4: - instead of introducing CONFIG_AF_UNIX, add fallback afunix.h header in os-win32.h, and compile the AF_UNIX stuff for all Windows hosts - drop CONFIG_AF_UNIX - introduce a new helper socket_check_afunix_support() to runtime-check the availability of AF_UNIX socket, and skip those appropriately Changes in v3: - drop the run-time check afunix_available() Changes in v2: - move #include <afunix.h> to os-win32.h - define WIN_BUILD_AF_UNIX only when CONFIG_WIN32 - drop #include <afunix.h> as it is now already included in osdep.h - new patch: tests/unit: Update test-io-channel-socket.c for Windows Bin Meng (4): util/qemu-sockets: Replace the call to close a socket with closesocket() util/qemu-sockets: Enable unix socket support on Windows chardev/char-socket: Update AF_UNIX for Windows tests/unit: Update test-io-channel-socket.c for Windows meson.build | 3 +++ include/sysemu/os-win32.h | 17 +++++++++++++ tests/unit/socket-helpers.h | 9 +++++++ chardev/char-socket.c | 4 ++-- tests/unit/socket-helpers.c | 16 +++++++++++++ tests/unit/test-io-channel-socket.c | 37 ++++++++++++++++++----------- util/qemu-sockets.c | 29 ++-------------------- 7 files changed, 72 insertions(+), 43 deletions(-) -- 2.34.1
