- * A VM status callback. Status plug-ins implement and register this
- * function using Dart_RegisterStatusPlugin. When Dart_GetVMStatus is
- * called, each callback is invoked to provide the requested information,
- * and the first one to do so "wins".
- *
- * Note: status requests execute outside of an isolate (which is why
- * handles aren't used).
- *
- * \param request an optional string that defines REST-like parameters
- *     to define what information is requested.
- *
- * \return Returns a valid JSON string, allocated from C heap. The caller
- *     is responsible for releasing this string. NULL is returned if the
- *     callback didn't handle that request.
