[Interest] Return value from QProcess

[Duane]

Qt 5.3, on TinyCore Linux 5 and Fedora 23.

I'm currently using a call to std::system to load a module with insmod. 
  This works but I would like to do it with QProcess.  This also works 
but I can't seem to get the return value of the insmod call like I can 
with std::system.  Any suggestions?
