Description
JSVAL_LOCK is a deprecated feature that is supported only for backward compatibility with existing applications. To lock a value, use local roots with JS_AddRoot.JSVAL_LOCK locks a JS value, v, to prevent the value from being garbage collected. v is a JS object, string, or double value.
JSVAL_LOCK determines if v is an object, string, or double value, and if it is, it locks the value. If locking is successful, or v already cannot be garbage collected because it is not an object, string, or double value, JSVAL_LOCK evaluates to true. Otherwise JSVAL_LOCK evaluates to false.
