aio-write

问题 My question is really simple. Why the code below does work on Linux, and doesn't on Mac OS X 10.6.2 Snow Leopard. To compile save the file to aio.cc, and compile with g++ aio.cc -o aio -lrt on Linux, and g++ aio.cc -o aio on Mac OS X. I'm using Mac OS X 10.6.2 for testing on a Mac, and Linux kernel 2.6 for testing on Linux. The failure I see on OS X is aio_write fails with -1 and sets errno to EAGAIN, which simply means "Resource temporarily unavailable". Why is that? extern "C" { #include

问题 Is there an easy way write to a file asynchronously in Python? I know the file io that comes with Python is blocking; which is fine in most cases. For this particular case, I need writes not to block the application at all, or at least as minimally as possible. 回答1: Twisted has non-blocking writes on file descriptors. If you're writing async code, I'd expect you to be using twisted, anyway. :) 回答2: As I understand things, asynchronous I/O is not quite the same as non-blocking I/O. In the case
