35 .Nd device driver module declaration macro
39 .Fn DEV_MODULE "name" "modeventhand_t evh" "void *arg"
43 macro declares a device driver kernel module.
46 structure and then calls
48 with the correct args, where
50 is the name of the module and
54 is the event handler for the module (refer to
56 for more information).
57 The event handler is supposed to create the device with
59 on load and to destroy it when it is unloaded using
63 #include <sys/module.h>
66 static struct cdevsw foo_devsw = { ... };
71 foo_load(module_t mod, int cmd, void *arg)
77 sdev = make_dev(&foo_devsw, 0, UID_ROOT, GID_WHEEL, 0600, "foo");
