  • Article

1/5/2010

This method copies a designated block of memory.

Syntax

HRESULT CopyMemoryX(
  DWORD dwCpuNum,
  LINEAR_MEM_MAP_TYPE lmt,
  ADDRESS_TYPE AddressSource,
  ADDRESS_TYPE AddressTarget,
  DWORD dwNbElem,
  BYTE bAccessWidthInBytes
);

Parameters

  • dwCpuNum
    [in] 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
    [in] 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
  • AddressSource
    [in]Starting address of the source memory block to be copied on the target device.
  • AddressTarget
    [in] Starting address of the target memory block to be overwritten on the target device.

  • dwNbElem
    [in]Number of elements of bAccessWidthInBytes to be copied.

    Note

    The server should handle copied blocks of at least 64 KB.

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

Return Value

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

Header eXDI2.h
Library ole32.lib, oleaut32.lib
Windows Embedded CE Windows CE 5.0 and later
