The JagGetCollection routine returns a reference to the specified collection. Once the component instance has retrieved a reference, the component object can lock and unlock the collection, create a new shared variable in the collection, or retrieve a reference to an existing shared variable.
If the collection exists, JAG_SUCCEED is returned and **ppCollection is set to the collection reference. If the collection does not exist, JAG_FAIL is returned and **ppCollection is set to NULL.
