Applies to: desktop apps only

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

Syntax

HRESULT Append(
  [in]   void const *pv,
  [in]   ULONG cb,
  [out]  ULONG *pcbWritten
);

Parameters

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

• cb [in]
  The number of bytes of data to attempt to append to the data in the buffer object.

• pcbWritten [out]
  Pointer to a ULONG that on return receives the actual number of bytes appended to the data in the buffer object.

Return value

This method can return one of these values.

• S_OK
  The data was successfully appended to the buffer object.

• FWX_E_BUFFERFULL
