DEVICE_SET_DESC(9)					   BSD Kernel Developer's Manual					DEVICE_SET_DESC(9)

NAME
device_set_desc, device_set_desc_copy, device_get_desc -- access the description of a device SYNOPSIS
#include <sys/param.h> #include <sys/bus.h> void device_set_desc(device_t dev, const char *desc); void device_set_desc_copy(device_t dev, const char *desc); const char * device_get_desc(device_t dev); DESCRIPTION
Manipulate the verbose description of a device. This description (if present) is printed as part of the message when it is attached during autoconfiguration. The variation device_set_desc_copy() is used to set the description if the string passed is a temporary buffer which will be overwritten. In this case, the system will copy the string, otherwise the pointer passed will be used directly. SEE ALSO

NAME
device -- an abstract representation of a device SYNOPSIS
typedef struct device *device_t; DESCRIPTION
The device object represents a piece of hardware attached to the system such as an expansion card, the bus which that card is plugged into, disk drives attached to the expansion card etc. The system defines one device, root_bus and all other devices are created dynamically during autoconfiguration. Normally devices representing top-level busses in the system (ISA, PCI etc.) will be attached directly to root_bus and other devices will be added as children of their relevant bus. The devices in a system form a tree. All devices except root_bus have a parent (see device_get_parent(9)). In addition, any device can have children attached to it (see device_add_child(9), device_add_child_ordered(9), device_find_child(9), device_get_children(9), and device_delete_child(9)). A device which has been successfully probed and attached to the system will also have a driver (see device_get_driver(9) and driver(9)) and a devclass (see device_get_devclass(9) and devclass(9)). Various other attributes of the device include a unit number (see device_get_unit(9)), verbose description (normally supplied by the driver, see device_set_desc(9) and device_get_desc(9)), a set of bus-spe- cific variables (see device_get_ivars(9)) and a set of driver-specific variables (see device_get_softc(9)). Devices can be in one of several states: DS_NOTPRESENT the device has not been probed for existence or the probe failed DS_ALIVE the device probe succeeded but not yet attached DS_ATTACHED the device has been successfully attached DS_BUSY the device is currently open The current state of the device can be determined by calling device_get_state(9).
