No, in this case open() blocks. cat is even not started, because the shell waits for open(). If you open /tmp/foo for reading, then open() suceeds, cat starts and may write. If you close the other end, the next write() from cat will return -1. Best regards, -- Tomasz Motylewski P.S. ALSA has more possible states of fd than pipes which may be just open/closed by the other side, and eventually full. This makes direct comparision difficult. ------------------------------------------------------- Sponsored by: AMD - Your access to the experts on Hammer Technology!
