Hi, I'm looking for a mechanism that allows one loadable kernel module to find the symbols of another module, i.e. find a function 'foo' by its name and get the address of it, so I can call it. I've stumbled across kernel objects which should allow me to do this using kobj_lookup_method(), but I haven't found a call to this function anywhere except where it's defined. kernel objects are used for parallel port drivers and sound drivers which use some kind of bus architecture with calls like BUS_ADD_CHILD() et.al. do I also have to use/implement such a bus architecture just to find some functions by their names? Is there a simpler method to just find the functions, or is there some more information on kernel objects (tutorial, simple example ...)? Any help is welcome. Thanx. elmar _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
