UStorage::ClassReleaseById

Decrements the reference count on one or more classes.
This function can be used on an object without the need to open it first.

Syntax

HRESULT ClassReleaseById(
[in] const ObjectId* p_poiObjectId,
[in] const stcClassRefCount* p_aClass,
[in] UINT32 p_ulCount,
[in] HANDLE p_hActionGroup
);

Parameter

p_poiObjectId [in]
Type: const ObjectId*
ID of the object to execute the action on.
p_aClass [in]
Type: const stcClassRefCount*
Array of stcClassRefCount structs specifying the classes and counts to increase the references on the object.
p_ulCount [in]
Type: UINT32
Number of elements in the p_aClass array.
p_hActionGroup [in]
Type: HANDLE
ActionGroup to use.

Return value

S_OK or an error from the Error Codes.
