create_bus_struct(9r)
NAME
  create_bus_struct - General: Creates a bus structure for the system
  (hardware) configuration tree

SYNOPSIS
  int create_bus_struct(
	  struct bus_config *bus_cnfg );

ARGUMENTS
  bus_cnfg
      Specifies a pointer to the bus_config structure associated with a
      specific bus. You set the members of the bus_config structure to
      appropriate values and then pass the address of the filled-in structure
      to the create_bus_struct routine.

DESCRIPTION
  The create_bus_struct routine creates a bus structure for each instance of
  a bus that the device driver supports. The routine integrates the bus
  structure for a specific bus into the list of bus structures that reside in
  the system configuration tree.

NOTES
  Typically, you supply the information needed by the create_bus_struct
  routine by passing to it the address of the filled-in bus_config structure.
  However, if any of this information needs to be configurable (that is, you
  want to give a system manager the ability to dynamically change this
  information), you must:

    ·  Define attributes for the information contained in the bus_config
       structure in the sysconfigtab file fragment

    ·  Define these attributes in the driver's cfg_subsys_attr_t data
       structure

    ·  Check these attribute definitions in the device driver's configure
       routine and appropriately modify the call to the
       create_bus_structroutine

RETURN VALUES
  Upon successful completion, create_bus_struct returns ESUCCESS. On failure,
  it returns EINVAL.
