From nwfilter_conf.c I call several functions of the nwfilter_gentech_driver.c from within an iterator callback function. Is the general right solution for this to have nwfilter_gentech_driver.c register an interface with nwfilter_conf.c that provides the addresses of those functions call from within nwfilter_conf.c now? If so, I think I could pass the callback function to the nwfilter_conf.c and move the actual callback function in nwfilter_gentech_driver.c and pass its address via the initialization function I call in nwfilter_conf.c from nwfilter_gentech_driver.c.
Thanks and regards,
