The Windows Process Status API (PSAPI) provides several methods for accessing system state information. For processes, the simplest and most common method is via the EnumProcesses() function, defined as follows:

BOOL EnumProcesses( DWORD*  pProcessIds
                  , DWORD   cb
                  , DWORD*  pBytesReturned);

pProcessIds points to an array into which the process identifiers of process objects in the system are returned. cb is the size of this array, measured in bytes. pBytesReturned points to a single variable that receives the number of bytes ...
