Not sure this is exactly your request, but you can register callbacks when
a capture is started / loaded / reloaded (when a preference changes for
example) and when it is closed with the following functions:

/**
 * Allow protocols to register "init" routines, which are called before
 * we make a pass through a capture file and dissect all its packets
 * (e.g., when we read in a new capture file, or run a "filter packets"
 * or "colorize packets" pass over the current capture file or when the
 * preferences are changed).
 */
WS_DLL_PUBLIC void register_init_routine(void (*func)(void));

/**
 * Allows protocols to register "cleanup" routines which are called
 * after closing a capture file (or when preferences are changed, in
 * that case these routines are called before the init routines are
 * executed). It can be used to release resources that are allocated in
 * register_init_routine.
 */
WS_DLL_PUBLIC void register_cleanup_routine(void (*func)(void));

Hope it helps,
Pascal.
