Cache item class.
A cache item is a structure holding information about a data object including a reference count that is used to control its lifetime. When you get a a cache item from the cache, you hold a reference that prevents the data from being released when the cache is full and something new is added. When you close the cache item, the reference count is decremented. The data object is destroyed when all cache items are closed and the cache releases its reference.
| void mlt_cache_item_close | ( | mlt_cache_item | item | ) |
