Device Driver Entry Points
Unit Delivery Routine
Exit
A unit delivery routine issues an RSB instruction to return control to the
SYSGEN autoconfiguration facility. If the routine returns error status in R0,
SYSGEN does not configure the unit.
Description
The unit delivery routine determines which units on a controller should be
configured. For instance, a unit delivery routine can prevent the creation of
UCBs for devices that do not respond to a test for their presence.
