GetSystemInfo
The GetSystemInfo function returns information about the current system. VOID GetSystemInfo(
  LPSYSTEM_INFO lpSystemInfo   // address of system information 
                               // structure
);typedef struct _SYSTEM_INFO { // sinf 
    union { 
        DWORD  dwOemId; 
        struct { 
            WORD wProcessorArchitecture; 
            WORD wReserved; 
        }; 
    }; 
    DWORD  dwPageSize; 
    LPVOID lpMinimumApplicationAddress; 
    LPVOID lpMaximumApplicationAddress; 
    DWORD  dwActiveProcessorMask; 
    DWORD  dwNumberOfProcessors; // HERE
    DWORD  dwProcessorType; 
    DWORD  dwAllocationGranularity; 
    WORD  wProcessorLevel; 
    WORD  wProcessorRevision; 
} SYSTEM_INFO;
