Detecting Programs

Posted by Matt Gerrans on October 18, 2001 at 5:26 PM

I think this is a operating system-specific thing. I know how you would do it in Windows or Unix, for instance, but it would be different on Mac (actually OS X is Unix) and others. In any case, you would need native methods to access the OS-specific implementation...

If you also writing (in C/C++ or whatever) the program that you are calling, you can make it single-instance (easy to do with a mutex), so that you can just exec() it whenever you need it and if it is already running, it won't run again.

> I want to know if it is possible to detect is a particular application is loaded and running in memory. The exec call allows you to run system programs, but is it possible program has already been loaded and running?
