MoveIn32 |
Reads a block of 32-bit data values from the specified address space and offset to local memory.
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;
[in] Address space from which to read the data.
[in] Offset within eSpace to read the data.
Data read from the register-based device.
Returns S_OK if successful, otherwise a failure HRESULT.
Reads a block of 32-bit values from a register-based device at the specified memory space and offset.
The following example demonstrates use of the MoveIn32 function.
// CoAcme4321.cpp STDMETHODIMP Acme4321::IAcme4321_Read(SAFEARRAY** ppsaData) { HRESULT hr = S_OK; hr = io.Memory.MoveIn32(VisaA32Space, 0x10, ppsaData); return hr; }
