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.
