Flushes the contents of the I/O write buffer to the device.

virtual HRESULT FlushWrite(bool bSendEnd = true, long lTimeout = CUR_TIMEOUT) sealed override;

Parameters

bSendEnd: [in] If true, the END signal is asserted with the last byte of the transfer. If false, no END signal is asserted.
lTimeout: [in] I/O timeout value in milliseconds.

Return Value

Returns S_OK if successful, otherwise a failure HRESULT.

Example

The following example demonstrates use of the FlushWrite function.

C++

Copy

// CoAcme4321.cpp
HRESULT Acme4321::Configure()
{
  HRESULT hr = S_OK;

  // Send an IEEE 488.2 END signal with the last byte in the buffer, use the existing timeout value
  hr = io.FlushWrite();

  return hr;
}
