Thank you Andre, Stefano and Ross.

It turns out that knowing the state of the process is not the problem. My 
simple application reads the standard output, as follows: 

 ui->textEdit->setText(myProcess->readAllStandardOutput());

Further reads are tacked onto the end of the text in the text edit box, which 
is not what I want. What I was trying to do was to have the process stop 
after the first read and a new process to start before subsequent reads.

I had tried clearing the text edit box before a read and terminating (I've 
also tried kill as well) the process after a read. It seems that what I really 
need to do is clear the standard output between reads. How do I do that?
