37 * This function should normally only be called as a callback on a successful
38 * pcap_cache_reload() or after a MSG_PRINTER_CAP message is received.
40 * This function can cause DELETION of printers and drivers from our registry,
41 * so calling it on a failed pcap reload may REMOVE permanently all printers
44 * @param[in] ev The event context.
46 * @param[in] msg_ctx The messaging context.
