Well I would assume that he just would use the glibc posix aio, which is suboptimal but at least the code can be reused. The bull project looks like it's trying to mimic posix aio on top of linux aio, so (if they got the details right) that should be faster. I didn't check their sources, though. You should be able to use the bull stuff with qemu, it would most likely overloading the glibc function for posix aio. > Which other OS do also support the POSIX AIO API? No idea really, but I would guess any "unixy" OS out there. -- Jens Axboe _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
