IFWXIOBuffer::Append

The Append method appends a specified number of bytes of data to the buffer object.

HRESULT Append(
  void const* pv,
  ULONG cb,
  ULONG* pcbWritten
);

Parameters

pv

[in] Pointer to the buffer that is appended to the buffer object.

cb

Return Values

S_OK

The data was successfully appended to the buffer object.

FWX_E_BUFFERFULL
