unconfigure_driver(9r)
NAME
  unconfigure_driver - General: Unconfigures a device driver that was
  dynamically configured

SYNOPSIS
  int unconfigure_driver(
	  char *bus_name,
	  int bus_num,
	  struct driver *driver_struct,
	  char *target_name,
	  int target_num );

ARGUMENTS
  bus_name
      Specifies the name of the bus to search for in the system configuration
      tree. You specified this name in a previous call to the
      configure_driver interface. You can specify the bus name or the
      wildcard constant DRIVER_WILDNAME.

  bus_num
      Specifies the bus number to search for in the hardware topology tree.
      You specified this number in a previous call to the configure_driver
      interface.

  driver_struct
      Specifies the address of the driver structure associated with the
      controlling device driver. The driver structure name is typically based
      on the device driver name. For example, the driver structure for the
      /dev/none driver is nonedriver. You set the members of the driver
      structure (usually in the driver's declaration section) to appropriate
      values and then pass the address of the filled in structure to
      unconfigure_driver.

  target_name
      Specifies the controller name to search for in the hardware topology
      tree. You specified this name in a previous call to the
      configure_driver interface.

  target_num
      Specifies the controller number to search for in the hardware topology
      tree. You specified this number in a previous call to the
      configure_driver interface.









DESCRIPTION
  The unconfigure_driver interface unconfigures a device driver that was
  dynamically configured into the kernel from the system (hardware)
  configuration tree. The unconfiguration tasks consist of marking the bus,
  controller, and device structures associated with the specific device
  driver as unused and available. The unconfigure_driver interface does not
  remove these structures from the hardware topology tree.

RETURN VALUES
  The unconfigure_driver interface can return one of the following constants
  defined in /usr/sys/include/sys/errno.h:

  ESUCCESS
	  The unconfigure_driver interface successfully unconfigured the
	  specified device driver.

  ENODEV  The unconfigure_driver interface cannot unconfigure the specified
	  device driver because there is no such device.
