    JS GetContextPrivate

    Access a JSContext field for application-specific data.


    void * JS_GetContextPrivate(JSContext *cx);
    void JS_SetContextPrivate(JSContext *cx, void *data);
    Name Type Description
    cx JSContext * Any context.
    data void * (in JS_SetContextPrivate) Pointer to application-defined data to be associated with the context cx.


    Each JSContext has a field of type void * which the application may use for any purpose. It is especially useful for storing data needed by callbacks. JS_GetContextPrivate gets this field and JS_SetContextPrivate sets it. The field is initially NULL.

    Memory management for this private data is the application's responsibility. The JavaScript engine itself never uses it.
