[Python-Dev] Asyncore .set_reuse_addr() on Windows (original) (raw)

Do any systems but win32 have SO_EXLUSIVEADDRUSE ? (and if they do, is it better than SO_REUSEADDR for the same reasons it is on win32?)

.. so why not write if hasattr(socket, 'SO_EXCLUSIVEADDRUSE'): reuse_constant = socket.SO_EXCLUSIVEADDRUSE else: reuse_constant = socket.SO_REUSEADDR

SO_EXCLUSIVEADDRUSE sounds like the exact opposite of SO_REUSEADDR, according to a page I found when trying to find out whether any other platform has SO_EXCLUSEIVEADDRUSE: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winsock/winsock/using_so_exclusiveaddruse.asp .. SO_REUSEADDR's semantics on Windows are apparently different from Unix, but SO_EXCLUSEIVEADDRUSE is different still.

I'm no win32-platform programmer, just trying to make sense of what I read on the web.
