ihandler_t(9s)
NAME
  ihandler_t - General: Contains information associated with device driver
  interrupt handling

SYNOPSIS
  ___________________________
  Member Name	Data Type
  ___________________________
  ih_id		ihandler_id_t
  ih_bus	struct bus *
  ih_bus_info	char *
  ___________________________

MEMBERS
  ih_id
      Specifies a unique ID. Device drivers do not use this member.

  ih_bus
      Specifies a pointer to the bus structure associated with this device
      driver. This member is needed because the interrupt dispatching
      methodology requires that the bus be responsible for dispatching
      interrupts in a bus-specific manner.

  ih_bus_info
      Specifies bus registration information.

DESCRIPTION
  The ihandler_t structure contains information associated with device driver
  interrupt handling. This model of interrupt dispatching uses the bus as the
  means of interrupt dispatching for all drivers.  For this reason, all of
  the information needed to register an interrupt is considered to be bus
  specific. As a result, no attempt is made to represent all the possible
  permutations within the ihandler_t data structure.

  Device driver writers pass the ihandler_t structure to the handler_add
  interface in the driver's probe interface to specify how interrupt handlers
  are to be registered with the bus-specific interrupt dispatcher.

  Device driver writers set the ih_bus_info member to the filled-in
  handler_intr_info structure, which contains the bus-specific information.
