Saves and restores frame chains.
Syntax
bool JS_SaveFrameChain(JSContext *cx); void JS_RestoreFrameChain(JSContext *cx);
| Name | Type | Description |
|---|---|---|
cx |
|
The context to query. |
Description
These two functions are used to set aside cx's call stack while that stack is inactive. After a call to JS_SaveFrameChain, it looks as if there is no code running on cx. Before calling JS_RestoreFrameChain, cx's call stack must be balanced and all nested calls to JS_SaveFrameChain must have had matching JS_RestoreFrameChain calls.
JS_SaveFrameChain deals with cx not having any code running on it.
