41 /* ------ USAGE -------
43 * In order to use this file from other extensions include it in every
44 * file where you need to call the eventloop API, also in the init
45 * function of your extension call Jim_ImportEventloopAPI(interp)
46 * after the Jim_InitExtension() call.
48 * See the UDP extension as example.
