There's a catch - windows also have support for this kind of functionality, called TransmitFile: \r\nhttps://learn.microsoft.com/en-us/windows/win32/api/mswsock/nf-mswsock-transmitfile\r\n\r\n# Pitch\r\n\r\nHaving this feature outside of asyncio (here it currently resides when using sock_sendfile, as link in \"previous discussion\" states) would help in closing the gap between what's supported on Windows and on POSIX OSes like macOS or Linux.\r\nBasic support for things like overlapped I/O (Windows acronym for asynchronous I/O) currently exists in lower level modules, like undocumented _overlapped module. Having this exposed in more user-friendly manner would give python better feature parity between various Tier-1 operating systems.\r\n\r\n# Previous discussion\r\n\r\nhttps://discuss.python.org/t/support-for-os-sendfile-for-windows/25020\r\n","author":{"url":"https://github.com/KhazAkar","@type":"Person","name":"KhazAkar"},"datePublished":"2023-03-22T09:01:54.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/102898/cpython/issues/102898"}
