i'm sorry, you're right about that. it returns the minimum number of frames that are available modulo the period size (i.e. the number of whole periods that can be processed at this time, expressed in frames). this is quite different than the current function of snd_pcm_wait(), which merely waits till a handle is ready (or has an error) according to poll. --p ------------------------------------------------------- This SF.NET email is sponsored by: Take your first step towards giving your online business a competitive advantage.
