Thx. I realise I now also need to understand the GIL and locking it and unlocking it.
Does anyone know of any links where blocking I/O calls are demonstrated in pure python? I'm currently parsing the c code for _socket.pyd and reading up on Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS. My goal is basically to produce a high performance socket that I can use with a Windows UI (wxpython) - so was thinking of calling ws2_32.dll but it looks like I might need to be a bit more careful. Any comments / pointers / help appreciated.

I think that sock.socket.fileno should get you the socket handle for the first parameter. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32 Visit our website at http://www.ubs.com This message contains confidential information and is intended only for the individual named.
