How is a busy spin better than a blocking read on a pipe? Also, since he is streaming, he needs a 'stream' (perhaps eventually, the write may not be so fast?). Either he would have to implement buffer management to get the desired stream functionality or go for something like a pipe. -aditya _______________________________________ Pune GNU/Linux Users Group Mailing List
