IeXdi2Mem::SearchMemoryX (Windows Embedded CE 6.0)

1/5/2010

This method searches memory for a block that matches a given sequence.

Syntax

HRESULT SearchMemoryX(
  [in] DWORD dwCpuNum,
  [in] LINEAR_MEM_MAP_TYPE lmt,
  [in] ADDRESS_TYPE AddressRangeStart,
  [in] ADDRESS_TYPE AddressRangeEnd,
  [in] DWORD dwNbElem,
  [in] BYTE bAccessWidthInBytes,
  [in, size_is(dwNbElem* bAccessWidthInBytes)] BYTE* pbSequenceToSearch,
  [out] ADDRESS_TYPE** ppAddressFound
);

Parameters

• dwCpuNum
  CPU number.

  This parameter should be 0 if this is not a symmetric multi-processor (SMP). Otherwise, assign dwCpuNum a value between 0 and n-1, where n is the CPU number in the SMP system.

• lmt
  Linear memory map type.

  The following memory map types are used by convention:

  Value	Description
  LMM_VIRT, 0	Virtual memory
  LMM_PHYS, 1	Physical memory
  LMM_IO, 2	Peripheral I/O
  3 and higher	Free for custom use

• AddressRangeStart
  Starting address of the memory block to be searched on the target device.

• AddressRangeEnd
  Ending address of the memory block to be searched on the target device.

• *dwNbElem   *
  Number of elements of bAccessWidthInBytes to be searched.

• bAccessWidthInBytes
  Data width in bytes, where byte=1, word=2, dword=4, and so on.

• pbSequenceToSearch
  Buffer containing the sequence to search.

  pbSequenceToSearch must be large enough to hold dwNbElem elements.

  Note

  The server should handle sequence buffers of at least 1 KB.

• ppAddressFound
  Pointer to first found address, if found. NULL if not found.

  The buffer for this value is allocated by CoTaskMemAlloc.

Return Value

The following table shows return values for this method.

Remarks

To avoid resource leaking, use CoTaskMemFree to free the task memory used by the buffer for ppAddressFound.
