What are the secrets to doing synchronous IO with FreeBSD? I have this application that I'm writing where I need to play a WAV file but I need to make sure all the bits are sent on there way before I move on. The WAV file is being played through a controller that I have to toggle some bits via a serial port to get the WAV file through. Without doing a sleep(3) and praying that IO is complete is there another way? I'm pretty sure what I need is the equivalent of O_SYNC in SVR4, but I think I'm drain-bamaged (sic) because I haven't found the equivalent in BSD. Thanks in advance. -steve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
