IeXdi2Mem::WriteMemoryX (Windows CE 5.0)
This method writes a block of data to linear memory.
HRESULT WriteMemoryX( [in] DWORDdwCpuNum, [in] LINEAR_MEM_MAP_TYPElmt, [in] ADDRESS_TYPEAddress, [in] DWORD dwNbElemToWrite, [in] BYTEbAccessWidthInBytes, [in, size_is(dwNbElemToWrite*bAccessWidthInBytes)] const BYTE*pbWriteBuffer, [out] DWORD* pdwNbElementEffectWritten);
Parameters
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 Address
Starting address of the data buffer to be accessed on the target.dwNbElemToRead
Number of elements of bAccessWidthInBytes to be accessed.bAccessWidthInBytes
Data width in bytes, where byte=1, word=2, dword=4, and so on.pbWriteBuffer
Buffer for writing.pbWriteBuffer must be at least large enough to hold dwNbElemToWrite elements.
**Note **The server should handle buffers of at least 64 KB.
pdwNbElementEffectWritten
Number of elements effectively written.If the entire address range is not accessible, such as when at least one element in the range encounters an access violation, this returned value should be 0 to avoid unnecessary querying.
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
The memory content provided to this function should be sanitized to remove artifacts of software breakpoints or other memory modifications produced by debugging activity in the driver, probe, or target device.
Requirements
OS Version: Windows CE 5.0 and later.
