C# Class inVtero.net.Mem

Physical to Virtual and Physical to Hypervisor Guest Virtual memory dump class Convienent generic interfaces for extracting preferred types * Type has to be a value/struct type and is expected to be 64 bits width * TODO: Adjust for other size structs & values stradling page boundries

Inheritance: IDisposable

Public Methods

Method	Description
Dispose ( ) : void	Dispose streams held in class instance
DumpPFNIndex ( ) : void
GetPageForPhysAddr ( HARDWARE_ADDRESS_ENTRY PAddr, long &block ) : long	Extract a single page of data from a physical address in source dump accounts for memory gaps/run layout
GetPageForPhysAddr ( HARDWARE_ADDRESS_ENTRY PAddr, long &block, bool &GotData ) : long
GetPageFromFileOffset ( long FileOffset, long &block, bool &DataRead ) : long	Get a pagesized block that contains the data from the byte offset specified
GetValueAtPhysicalAddr ( HARDWARE_ADDRESS_ENTRY PAddr ) : long	Get a long back for the address specified
InitMem ( String mFile, AMemoryRunDetector Detector, uint BitmapArray = null ) : Mem
Mem ( Mem parent ) : System
OffsetToMemIndex ( long aPFN ) : long	Code to convert a PFN, which is based on file offset >> PAGE_SHIFT, into an indexed PFN. Physical memory is meant to have "gaps" historically reserved for hw interactions. This means we need to adjust the byte offset into an index accounting for gaps. TODO: Something similar is needed to natively support "extent" based sources.
RawOffsetToPFN ( long offset ) : long
VirtualToPhysical ( HARDWARE_ADDRESS_ENTRY eptp, HARDWARE_ADDRESS_ENTRY aCR3, long Addr ) : HARDWARE_ADDRESS_ENTRY
VirtualToPhysical ( HARDWARE_ADDRESS_ENTRY aCR3, long Addr ) : HARDWARE_ADDRESS_ENTRY
