WriteClassStm function (coml2api.h)

The WriteClassStm function stores the specified CLSID in the stream.

Syntax

HRESULT WriteClassStm(
  [in] LPSTREAM pStm,
  [in] REFCLSID rclsid
);

Parameters

[in] pStm

IStream pointer to the stream into which the CLSID is to be written.

[in] rclsid

Specifies the CLSID to write to the stream.

Return value

This function returns HRESULT.

Remarks

The WriteClassStm function writes a CLSID to the specified stream object so it can be read by the ReadClassStm function. Most applications do not call WriteClassStm directly. OLE calls it before making a call to an object's IPersistStream::Save method.
