A snapshot that includes the process list contains information about each currently executing process. You can retrieve information for the first process in the list by using the Process32First function. After retrieving the first process in the list, you can traverse the process list for subsequent entries by using the Process32Next function. Process32First and Process32Next fill a PROCESSENTRY32 structure with information about a process in the snapshot. For an example, see Taking a Snapshot and Viewing Processes.
