A table used to define device monitoring. A row in this table is
created by setting any read-write member, indexed by the next
available index (a3ComPollNextFreeIndex). An entry in this table is
deleted by setting a3ComPollAction to destroy(5). An example of the
indexing of this table is a3ComPollRate.2 This method of creation
makes the table very user friendly, although a bit harder to detect
racing conditions. The suggested method for racing condition
detection is by checking the a3ComPollAddress and a3ComPollOwner
objects while the a3ComPollReport object is set to active.
