wp_die_jsonp_handler WordPress Filter Hook

The wp_die_jsonp_handler hook is triggered when a JSONP response is required for a WP_Error object. This hook allows for a custom function to be defined which will handle the JSONP response. The function must take two arguments: the WP_Error object, and the callback function name.
