Parameters

eSpace

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

ullOffset

[in] Offset within eSpace to write the value.

uVal

Value to write to the register-based device.

Return value

Returns S_OK if successful, otherwise a failure HRESULT.

Remarks

Writes a 16-bit value to a register-based device at the specified memory space and offset.

Example

The following example demonstrates use of the Out16 function.

STDMETHODIMP Acme4321::IAcme4321_WriteRegister(short sVal)
{
  HRESULT hr = S_OK;

  UINT16 uVal = sVal;
  hr = io.Memory.Out16(VisaA16Space, 0x10, sVal);

  return hr;
}
