Parameters

• pStream
  [in] The stream to be wrapped. If NULL, the current base stream is released and any associated resources are released.

• fSetFormatToBaseStreamFormat
  [in] Flag specifies that the converter's stream format will be set to the same format as the base stream (set up as a pass through).

  If pStream == NULL and this is set to TRUE, the format converter's stream format is reset to be undefined.

• fWriteToBaseStream
  [in] If TRUE, data will be written to the base stream. If FALSE, data will be read from the base stream. The format converter can only be in one I/O mode or the other at a time.
