I am running into a problem when the binary to be executed contains
a scanf statement. I want the user to see results and type in input
in real time (like the debugger for standard C tools in xcode). The
issue is that as soon as the task hits the scanf statement, the read
pipe blocks, so I can't read from it to get data to that point, nor
can I tell when it blocks in order to prompt the user for input
(preferably using the output up to that point). I know it can be
done, I am just completely in the dark as to how/what classes to
consider.
Any ideas on how to accomplish what I'm after?
You may have to use a pseudo-terminal (ptty) rather than pipes to
achieve what you're after.
