Identify a process in memory

How do I identify if a process is currently running in memory, in a Windows NT or Windows 98 machine? (How does the task manager show us the current process information?)
To identify programatically using C.
I want only one instance of my application running at a point of time.

Go to msdn.microsoft.com and search for psapi (process status api). You probably want to look at EnumProcesses() first. This returns the list of pid's and OpenProcess(pid) will give you a handle to the process. With this you can find anything out about a given process (assuming you have enough security privileges).

Why was it a fatal mistake? Are you going to hunt me down with an AK-47 or something?

It's just an expression. Chill out dude. I was just trying to make the point that if people have a question about how to solve a problem, they should simply verify they are taking the correct approach by asking a more general question. Once they are sure they are using the right approach, then they can worry about how to solve their implementation problems. No worries.

Nothing has happened on this question in more than 9 months. It's time for cleanup!

My recommendation, which I will post in the Cleanup topic area, is to

Thanks for the recommendation. I will follow it. I had seen some experts (who have been using EE for a long time and who have plenty of expert points) doing it, so I thought that there is nothing wrong with it. But I guess it is against some policies.
