I know how to implement mmap through character device. But I am working with network driver. Network devices doesn't appear in file system and they don't have any interface for mmaping.
I think I can try to solve with task with: vm_map_lookup - to get a vm_object of allocated space and then vm_map_find (map_of_process, ... founded_object ...) - allocate a new space in the vms of process. I try to do it now with a small hope of success :-) > -- > Alexander Kabaev -- Alexej Sokolov <[EMAIL PROTECTED]> _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
