Field Detail

### processorArchitecture

    public WinBase.SYSTEM_INFO.UNION.ByReference processorArchitecture

  Processor architecture.

### dwPageSize

    public WinDef.DWORD dwPageSize

  Page size and the granularity of page protection and commitment.

### lpMinimumApplicationAddress

    public Pointer lpMinimumApplicationAddress

  Pointer to the lowest memory address accessible to applications and dynamic-link libraries (DLLs).

### lpMaximumApplicationAddress

    public Pointer lpMaximumApplicationAddress

  Pointer to the highest memory address accessible to applications and DLLs.

### dwActiveProcessorMask

    public BaseTSD.DWORD_PTR dwActiveProcessorMask

  Mask representing the set of processors configured into the system. Bit 0 is processor 0; bit 31 is processor 31.

### dwNumberOfProcessors

    public WinDef.DWORD dwNumberOfProcessors

  Number of processors in the system.

### dwProcessorType

    public WinDef.DWORD dwProcessorType

  An obsolete member that is retained for compatibility with Windows NT 3.5 and Windows Me/98/95. Use the wProcessorArchitecture, wProcessorLevel, and wProcessorRevision members to determine the type of processor. PROCESSOR_INTEL_386 PROCESSOR_INTEL_486 PROCESSOR_INTEL_PENTIUM

### dwAllocationGranularity

    public WinDef.DWORD dwAllocationGranularity

  Granularity for the starting address at which virtual memory can be allocated.

### wProcessorLevel

    public WinDef.WORD wProcessorLevel

  System's architecture-dependent processor level. It should be used only for display purposes. To determine the feature set of a processor, use the IsProcessorFeaturePresent function. If wProcessorArchitecture is PROCESSOR_ARCHITECTURE_INTEL, wProcessorLevel is defined by the CPU vendor. If wProcessorArchitecture is PROCESSOR_ARCHITECTURE_IA64, wProcessorLevel is set to 1.

### wProcessorRevision

    public WinDef.WORD wProcessorRevision

  Architecture-dependent processor revision.
