| Name | Type | Description |
|---|---|---|
cx |
JSContext * |
The context to destroy. |
Description
These functions destroy a context, cx. JS_DestroyContext additionally performs garbage collection to reclaim any memory that was being used by cx's global object. JS_DestroyContextNoGC does not perform garbage collection. JS_DestroyContextMaybeGC may or may not perform garbage collection; the engine makes an educated guess as to whether enough memory would be reclaimed to justify the work.
In a JS_THREADSAFE build, it does not matter whether the calling thread is in a request on cx. However, there must not be any suspended requests on cx.
If JS_SetContextCallback has been called, this calls the callback.
