MoveIn32

Reads a block of 32-bit data values from the specified address space and offset to local memory.

Syntax

virtual HRESULT MoveIn32(VisaAddressSpace eSpace, UINT64 ullOffset, UINT32 ulLength, UINT32* pBuf) abstract;

        virtual HRESULT MoveIn32(VisaAddressSpaceeSpace, UINT64 ullOffset, UINT32 ulLength, SAFEARRAY** pBuf) abstract;

        virtual HRESULT MoveIn32(VisaAddressSpaceeSpace, UINT64 ullOffset, UINT32 ulLength, CComSafeArray<UINT32>& pBuf) abstract;

Parameters

eSpace

[in] Address space from which to read the data.

ullOffset

[in] Offset within eSpace to read the data.

pBuf

Data read from the register-based device.

Return value

Returns S_OK if successful, otherwise a failure HRESULT.

Remarks

Reads a block of 32-bit values from a register-based device at the specified memory space and offset.

Example

The following example demonstrates use of the MoveIn32 function.

STDMETHODIMP Acme4321::IAcme4321_Read(SAFEARRAY** ppsaData)
{
  HRESULT hr = S_OK;

  hr = io.Memory.MoveIn32(VisaA32Space, 0x10, ppsaData);

  return hr;
}
