NAME
	GetDefDiskObject - read default wb disk object from disk.       (V36)

   SYNOPSIS
	diskobj = GetDefDiskObject(def_type)
	  D0                          D0

	struct DiskObject *GetDefDiskObject(LONG);

   FUNCTION
	This routine reads in a default Workbench disk object from disk.
	The valid def_types can be found in workbench/workbench.h and
	currently include WBDISK thru WBKICK. If the call fails,
	it will return NULL. The reason for the failure may be obtained
	via IoErr().

	Using this routine protects you from any future changes to
	the way default icons are stored within the system.

   INPUTS
	def_type -- default icon type (WBDISK thru WBKICK).

   RESULTS
	diskobj -- the default Workbench disk object in question

   NOTES
	icon.library V36 through V40 did not support the WBDEVICE default
	icon type.
