Operating System Routines
IOC$RELDATAP
If the data path wait queue contains waiting fork processes, IOC$RELDATAP
dequeues the first process, allocates the data path to it, restores R3 through
R5, and reactivates it. Otherwise, it marks the path available by setting the
corresponding bit in the data path bit map (ADP$W_DPBITMAP), and returns to
its caller.
If the bit map has been corrupted, IOC$RELDATAP issues an INCONSTATE
bugcheck.
