This is an INIT which allows a user to assign special ICN#s to their
disks.
It installs a patch to Control which watches for the "give-me-an-icon"
call to mountable volumes.
If the call is being made to a driver in the drive queue, it checks to
see if that drive/driver
combination appears in any VCB entry. If it does, the volume name is
extracted from the VCB
and compared against Facade's dictionary of named ICN#s (loaded at
INIT time). If a match
is found, the patch returns the address of the dictionary entry
instead of the driver's icon.
Since the dictionary lookup is performed every time the right Control
call is made, a disk's
icon can be changed by simply changing the name (and then making the
Finder re-draw it by
selecting and/or moving it). I've got icons for all the different
servers I mount on a regular
basis. HDs, floppies, tapes, AppleShare volumes, etc can all have
custom icons.
Place named ICN#s into the INIT file for each volume you want to
"dress up."
Facade successfully returns an icon pointer even if the driver being
called doesn't support
the proper Control calls.
