JsSetObjectBeforeCollectCallback

Sets a callback function that is called by the runtime before garbage collection of an object.
STDAPI_(JsErrorCode)
JsSetObjectBeforeCollectCallback(
_In_ JsRef ref,
_In_opt_ void *callbackState,
_In_ JsObjectBeforeCollectCallback objectBeforeCollectCallback);
- ref: The object for which to register the callback.
- callbackState: User provided state that will be passed back to the callback.
- objectBeforeCollectCallback: The callback function being set. Use null to clear previously registered callback.
The code JsNoError if the operation succeeded, a failure code otherwise.
The callback is invoked on the current runtime execution thread, therefore execution is blocked until the callback completes.
