WINOLEAPI ReadClassStm(

CLSID * pclsid	//Pointer to where the CLSID is to be written
);

Parameters

pStm

[in] Pointer to the IStream interface on the stream object containing the CLSID to be read. This CLSID must have been previously written to the stream object using WriteClassStmEVYOCB.

pclsid

[out] Pointer to where the CLSID is to be written.

This function also returns any of the error values returned by the IStream::Read4QE_N8 method.

Remarks

Most applications do not call the ReadClassStm method directly. OLE calls it before making a call to an object s IPersistStream::Load5_OA0S implementation.
