This function stores the specified CLSID in a storage object.

Syntax

WINOLEAPI WriteClassStg(
  IStorage* pStg,
  REFCLSID rclsid 
);

Parameters

• pStg
  [in] IStorage pointer to the storage object that gets a new CLSID.

• rclsid
  [in] CLSID to be stored with the object.

Return Value

• S_OK
  Indicates the CLSID was successfully written to the file.

• STG_E_MEDIUMFULL
  Indicates the CLSID could not be written due to lack of memory.

This function also returns any of the error values returned by the IStorage::SetClass method.

Remarks

Passing into this function any invalid and, under some circumstances, NULL pointers results in unexpected termination of the application.

The WriteClassStg function writes a CLSID to the specified storage object so it can be read by the ReadClassStg function. Container applications typically call this function before calling the IPersistStorage::Save method.
