What if a subprocess disconnects stdin and/or stdout?

Show all headers | View raw

I am writing "Command Communication Library":
https://github.com/vporton/libcomcom

The most immediate purpose is to (synchronously as of the planned first 
release):

Run an OS command with the given string written to stdin and with stdout 
returned (as a string) to the caller after the command finished.

It is clear what to do if the child process exits.

But what if the child process does NOT exit but closes stdin and/or stdout? 
What should I do in this case? Should I kill the process? Should I wait when 
it finishes? Should I return the stdout now, even despite the process has 
not yet finished?

P.S. This libcomcom is a VERY long time should be already have been written. 
I wonder if I am the first person who solves this problem.
