I never tried this. But maybe the following works?
#include <signal.h>
::kill(p.pid(), SIGSTOP);
::kill(p.pid(), SIGCONT);
Assuming p is of type QProcess and this is a POSIX-compliant OS.
A related question may be, whether QProcess is creating a new
process group or not. If it does, I would use -p.pid() to address
the whole process group.

Hi,
I have created a QProcess and this is starting a backend
process. I want to pause and resume this process and also
stop this process at some point of time. Can anybody
suggest me how to do that?
Regards,
Rekha.
