Can anyone tell me what I am dong wrong.
In this case, I'd close the pipe when you're done.
pipes.stdin().writeln("Hello world");
pipes.stdin.close;
myecho loops on stdin until it receives everything; until the
pipe is closed.
testpipes waits for myecho to complete before termination.
The two processes are waiting on each other: testpipes won't
close the file until it exits, and myecho won't exit until
testpipes closes the file.
an explicit call to close breaks the deadlock.
In this case, flushing would cause the one line to appear,
because of the buffering yazd talked about, but the program
still wouldn't terminate since a flushed buffer still
potentially has more coming so echo would see that line, then
wait for more..
Thank you Adam, and yazd for your responses, now it works.
Thanks also for the explanations, I was wondering how myecho.d
would know when the input was finished so it could terminate.
