I have a question for the experts. Is there a standard field in all
records in which detailed device status (status from device support)
may be placed where is is accessible by a database get operation.
My particular difficulty appears with asynchronous device support
for the MIL/STD1553B bus. We have a controller for the 1553 bus which
generates an interrupt at the end of a bus transaction. The 1553 bus
driver reschedules record "processing" (PACT is non-zero at this point) at
interrupt time via a call to callbackRequestProcessCallback, passing a
longword with bus I/O completion status. I need to save this status in
a standard record field (one that all records have) so that, if there
was an error, the application program may retrieve it. Any
suggestions?
