- label specifies the counters of interest - it is a case-insensitive, substring match. An empty string matches any counter that is capable of triggering an action when it expires: purely informational counters are ignored in this case.
- minTurns and maxTurns specify the endpoints (inclusive) of the range to be checked. Passing the same value for both checks for an expiration on that specific turn.
Determines if a counter will expire in a specified period of time.
Return value is an empty string if there are no matching counters; the counter name if there is only one; or a tab-delimited list of names if there were multiple matches.
The CLI command "counters" can be used to show, clear, or add to current turn counters.
