Re: Why isastream() alway returns 0?

Hi,

It seems that calling isastream( fd ) on many /dev/xxx such /dev/tty0
always return 0, means not a stream. What's wrong with it?

Perhaps because none of these devices, and actually nothing in Linux, is implemented using the UNIX System 5 streams, so this functiona will always return 0?
