Out64

Writes a 64-bit value to a register-based device.

virtual HRESULT Out64(VisaAddressSpace eSpace, UINT64 ullOffset, UINT64 uVal) abstract;

eSpace

[in] Address space to which the value will be written.

ullOffset

[in] Offset within eSpace to write the value.

uVal

Value to write to the register-based device.

Returns S_OK if successful, otherwise a failure HRESULT.

Writes a 64-bit value to a register-based device at the specified memory space and offset.

The following example demonstrates use of the Out64 function.

CoAcme4321.cpp
STDMETHODIMP Acme4321::IAcme4321_WriteRegister(UINT64 uVal)
{
HRESULT hr = S_OK;
hr = io.Memory.Out64(VisaA64Space, 0x10, uVal);
return hr;
}
