function registerTimedReportCallback( $callback )
es
function registerTimedReportCallback( callback )
The callback is invoked only during the execution of
ySleep
or
yHandleEvents
. This provides
control over the time when the callback is triggered. For good responsiveness, remember to call one of
these two functions periodically. To unregister a callback, pass a null pointer as argument.
Parameters :
callback the callback function to call, or a null pointer. The callback function should take two arguments:
the function object of which the value has changed, and an YMeasure object describing the new
advertised value.
