JS_SetAllNonReservedSlotsToUndefined

This article covers features introduced in SpiderMonkey 24

Assign undefined to all of the object's non-reserved slots.

Note: This is done for all slots, regardless of the associated property descriptor.

Syntax

void
JS_SetAllNonReservedSlotsToUndefined(JSContext *cx, JSObject *objArg);
Name Type Description
cx JSContext * The context in which to clear the object. Requires request. In a JS_THREADSAFE build, the caller must be in a request on this JSContext.
obj JSObject * Object from which to delete all properties.
