- - ### Field Detail

    - #### processorArchitecture

          public WinBase.SYSTEM_INFO.UNION processorArchitecture

      Processor architecture (unnamed union).

    - #### 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.

  - ### Constructor Detail

    - #### SYSTEM_INFO

          public SYSTEM_INFO()
