WriteClassStm

Stores the specified CLSID in the stream.

WINOLEAPI WriteClassStm(

IStream * pStm,

//Points to the IStream interface on the stream object

REFCLSID rclsid

//Specifies the CLSID to be stored in the stream object

);

Parameters

pStm: [in] IStream pointer to the stream into which the CLSID is to be written.
rclsid: [in] Specifies the CLSID to write to the stream.

Return Values

S_OK: Indicates the CLSID was successfully written.
STG_E_MEDIUMFULL: The CLSID could not be written because there is no space left on device.

IStorage::SetClass method error return values.

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.
