Well.. i don't have any public 'hosting', but I put it in here: http://www.4shared.com/dir/LHn_I393/sharing.html Also, the code is as simple as: 1 #include <sys/param.h> 2 #include <sys/kernel.h> 3 #include <sys/module.h> 4 5 6 char *str = "THIS IS A STR MARKING DATA START"; 7 8 static int kms_null_handler(module_t m, int op, void *data) 9 { 10 return (0); 11 } 12 13 static moduledata_t kms_null_data = { 14 "kms_null", 15 kms_null_handler, 16 NULL, 17 }; 18 19 DECLARE_MODULE(kms_null, kms_null_data, SI_SUB_EXEC, SI_ORDER_ANY); It is being compiled on i386/GENERIC kernel. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
