IeXdi2Mem::SearchMemoryX (Windows CE 5.0)
This method searches memory for a block that matches a given sequence.
HRESULT SearchMemoryX( [in] DWORDdwCpuNum, [in] LINEAR_MEM_MAP_TYPElmt, [in] ADDRESS_TYPEAddressRangeStart, [in] ADDRESS_TYPEAddressRangeEnd, [in] DWORDdwNbElem, [in] BYTEbAccessWidthInBytes, [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 Values
The following table shows return values for this method.
| Value | Description |
|---|---|
| S_OK | Indicates the function was successful. |
| E_FAIL | Indicates an unspecified failure. |
| E_OUTOFMEMORY | Indicates an out of memory error. |
| E_INVALIDARG | Indicates one or more invalid arguments. |
| EXDI_E_COMMUNICATION | Indicates a communication error between host driver and debugging target. |
| EXDI_E_ACCESSVIOLATION | Indicates an access violation occurred on at least one element in the address range specified by the operation. |
Remarks
To avoid resource leaking, use CoTaskMemFree to free the task memory used by the buffer for ppAddressFound.
Requirements
OS Version: Windows CE 5.0 and later.
