Hi, is there a simple way to issue a non-blocking read to a regular file ? Ideally, I would like a nbread(handle, buf, count); which would start reading from the disk, and could then notify the completion of I/O via select(). I don't know if fcntl() is enough: you can specify O_NONBLOCK for the file, but then I have no idea if select() on that descriptor would return immediately or will wait for at least one/the desired amound of bytes to be available.
