BusyWait - wait for a datapoint to achieve a value
BusyWait
monitors a datapoint by polling dbman for its value once per second. The
datapoint is polled for a maximum number of tries or until the datapoint
has achieved the desired value.
This function should only be used on a database
connection where no subscriptions have been posted. If a parameter has been
subscribed to and a change occurs while this function is in use the resulting
message from dbman will confuse operation.
This function is part of libmngr.
