how to detect a process is already running in memory in QT [duplicate]

Question

I am beginner to QT. I am working on a QT application. I have to run a list of processes if it is not running in the memory. The problem is how can i detect a process is already running in the memory or not. For example i have a process name abc than how can i detect it is already running. Something i need is like

QProcess *p = new QProcess(); int status = p->start("check if abc is running or not");

@Arun i searched for it will show if the QProcess instance is running a process i need to find if the process 'abc' is running in the memory where abc is the process name — Noor

Maybe you can use the QMutex.
