Well !! That's far more than the things I'm having trouble with!! I'm not being able to make ONE asynchronous read. I've tried the aio functions with file I/O and it worked fine, I've also tried the socket I/O with read() and it worked fine too. But when I issue the read to the async queue an try to get its status aio_error returns -1 and sets errno to EINVAL. Anyway this is a test program just to become familiar with the fucntions before actually using them, so I really need more information about them, and the aiocb_t struct. Thanks for your answer.

Its best to be using -current from my experience. TCP sockets should work, but they'll be pretty crippled for certain kinds of uses (like trying to have an outstanding read on more than a couple dozen sockets, etc). I've got a set of patches that fix this and the fact that signals don't get issued for completion on certain types of requests. I'm hoping to get it committed, but feel free to contact me for the latest stuff until then. I just finished updating and consolidating my patches so they cleanly apply to -current of a week ago. Testing thus far appears promising--I'm balancing more than a few sockets and pushing 10MB/sec through them (disk to socket and the inverse). I killed the last bug I knew of this week (occasionally paniced under some wierd process shutdown conditions). I hope to try 1000 descriptors soon. -Chris +------------------------------+-----------------------------------+ |Ricardo Bernardini | "No entiendo por que todos ponen | |rbernardini@hotmail.com | alguna frase celebre aqui" | |+54-11-4404-4525 | "I don't understand why everybody | |Buenos Aires, Argentina | puts a quote in here" | +------------------------------+-----------------------------------+ ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
