Is there any way to have one program run another arbitrary program
with input from stdin and display the output as if you had run it in
a shell (i.e., you'd see some of the output followed by the input
they typed in and then a newline because they pressed return followed
by subsequent output, etc.).
I can't use readline with the pipe because I don't know how much
output the arbitrary program has before it calls an input statement.
I've googled and understand that calling read() will deadlock when
the program is waiting for input.
When I first write all the input to the input pipe and then call read
on the output pipe it works just the same as if I had run the program
as: program < input_file
What I'd like to see is the input intermixed with the output as if
the user had typed it in.
Thanks,
Dave
