I/O Map-Entry
Status Words
The ControlNet status file is an integer data-table file that you specify
and configure with the I/O map for scheduled-I/O usage. It contains
status information about all of the ControlNet network’s scheduled
I/O connections. Each I/O map-table entry has a status-file offset field
pointing to three status words associated with the connection.
