Question

I am looking for a method of piping input from one program into another continuously. Can iNotify or file polling be used on stdin or am I better off using a temp file.

Edit

Sorry for not indicating that it was in reference to a shell pipe NOT a Pipe(2).

Answer 1

Pipes already operate continuously. If you run prog1 | prog2, every time prog1 writes more output to stdout, prog2 will see this on stdin and be able to read it. prog2 won’t see an end of file on the pipe until prog1 closes its side of the pipe (or exits, which does the same thing).
