Hello!
I'm using pipeProcess() to create a process:
pipes = pipeProcess(["bash", "-c", BASH_COMMAND], 
Redirect.stdin | Redirect.stdout | Redirect.stderr);

Is it possible detect that the child is waiting for input on 
stdin?
I can't find decision even for C. I think it is impossible if 
the child uses unblocking reading. But I want to detect 
blocking reading.

If blocking is an error, you could close stdin and assuming the 
process checks the error codes correctly....
