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.

Windows CE: Passing into this function any invalid and, under some circumstances, NULL pointers will result in unexpected termination of the application. For more information about handling exceptions, see Programming Considerations.
