CPersistStream::Save

Saves the filter's data to the given stream.

Syntax

  HRESULT Save(
    LPSTREAM pStm,
    BOOL fClearDirty
);

Parameters

pStm

Pointer to the stream to which data is to be saved.

fClearDirty

Flag that indicates whether to reset the current stream's dirty flag; TRUE means to reset it. (When the method is called as part of a Save operation, the value is typically TRUE; when called as part of a Save As operation, the value is typically FALSE.)

Return Value

Returns an HRESULT value.

Remarks

This member function implements the IPersistStream::Save method. It calls WriteInt with the software version, calls CPersistStream::WriteToStream with the stream in pStm, and resets mPS_fDirty.

Requirements

**  Header:** Declared in Pstream.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
