42 macro declares a device driver kernel module.
45 structure and then calls
47 with the correct args, where
49 is the name of the module and
53 is the event handler for the module (refer to
55 for more information).
56 The event handler is supposed to create the device with
58 on load and to destroy it when it is unloaded using
62 #include <sys/module.h>
65 static struct dev_ops foo_ops = { ... };
70 foo_load(module_t mod, int cmd, void *arg)
74 dev_ops_add(&foo_ops, ...);

80 /* We must obtain a reference to sdev, so we can destroy it later */
88 /* The same mask and match must be specified, as in dev_ops_add() */
89 dev_ops_remove(&foo_ops, ...);
