		The address of a pointer.

		A  handle to a device  node.

       These functions extract information associated with a device node.

       The  di_binding_name()  function returns a pointer to the binding name.
       The binding name is the name used by the system to select a driver  for
       the device.

       The  di_bus_addr()  function  returns  a	 pointer  to a null-terminated
       string containing the assigned bus address  for	the  device.  NULL  is
       returned	 if a bus address has not been assigned to the device. A zero-
       length string may be returned and is considered a valid bus address.

       The return value of di_compatible_names() is the number	of  compatible
       names. names is updated to point to a buffer contained within the snap‐
       shot. The buffer contains a concatenation of  null-terminated  strings,
       for example:


       See  the	 discussion  of	 generic names in Writing Device Drivers for a
       description of how compatible names are	used  by  Solaris  to  achieve
       driver binding for the node.

       The di_devid() function returns the device ID for node, if it is regis‐
       tered. Otherwise, a null pointer is returned. Interfaces in the	libde‐
       vid(3LIB)  library  may	be used to manipulate the handle to the device
       id. This function is obsolete  and  might  be  removed  from  a	future
       Solaris release. Applications should use the "devid" property instead.

       The  di_driver_name()  function returns the name of the driver bound to
       the node. A null pointer is returned if	 node  is  not	bound  to  any

       The  di_driver_ops()  function  returns	a  bit array of	 device driver
       entry points that are supported by the driver bound to this node.  Pos‐
       sible  bit  fields  supported  by the driver are DI_CB_OPS, DI_BUS_OPS,

       The di_driver_major() function returns the major number associated with
       the driver bound to node. If there is no driver bound to the node, this
       function returns −1.

       The di_instance() function returns the instance number of the device. A
       value  of  -1 indicates an instance number has not been assigned to the
       device by the system.

       The di_nodeid() function returns	 the type of device, which may be  one
       of the following possible values: DI_PSEUDO_NODEID, DI_PROM_NODEID, and
       DI_SID_NODEID. Devices of type DI_PROM_NODEID may have additional prop‐
       erties  that  are  defined by the PROM. See di_prom_prop_data(3DEVINFO)
       and di_prom_prop_lookup_bytes(3DEVINFO).

       The di_node_name() function returns  a  pointer	to  a  null-terminated
       string containing the node name.

       See di_init(3DEVINFO) for an example demonstrating typical use of these

       See attributes(5)  for descriptions of the following attributes:
