.Dd January 19, 2012 .Dt DEV_MODULE 9 .Os .Sh NAME .Nm DEV_MODULE .Nd device driver module declaration macro .Sh SYNOPSIS n sys/param.h n sys/kernel.h n sys/module.h n sys/conf.h .Fn DEV_MODULE "name" "modeventhand_t evh" "void *arg" .Sh DESCRIPTION The .Fn DEV_MODULE macro declares a device driver kernel module. It fills in a .Vt moduledata_t structure and then calls .Fn DECLARE_MODULE with the correct args, where .Fa name is the name of the module and .Fa evh (with its argument .Fa arg ) is the event handler for the module (refer to .Xr DECLARE_MODULE 9 for more information). The event handler is supposed to create the device with .Fn make_dev on load and to destroy it when it is unloaded using .Fn destroy_dev . .Sh EXAMPLES d -literal #include <sys/module.h> #include <sys/conf.h> static struct cdevsw foo_devsw = { ... }; static struct cdev *sdev; static int foo_load(module_t mod, int cmd, void *arg) { int err = 0; switch (cmd) { case MOD_LOAD: sdev = make_dev(&foo_devsw, 0, UID_ROOT, GID_WHEEL, 0600, "foo"); break; /* Success*/ case MOD_UNLOAD: case MOD_SHUTDOWN: destroy_dev(sdev); break; /* Success*/ default: err = EINVAL; break; } return(err); } DEV_MODULE(foo, foo_load, NULL); .Ed .Sh SEE ALSO .Xr DECLARE_MODULE 9 , .Xr destroy_dev 9 , .Xr make_dev 9 , .Xr module 9 .Sh AUTHORS This manual page was written by .An Alexander Langer Aq alex@FreeBSD.org .
