A customer wanted to know what the difference is between
CreateTimerQueueTimer
and
SetThreadpoolTimer,
and what factors they should consider when choosing between them.
(The customer explained that their immediate need was to create
a periodic timer that fires every five seconds.
It is not critical that the timer fire exactly at five second intervals.)
The
CreateTimerQueueTimer
function is a wrapper that calls
SetThreadpoolTimer
under the covers,
so at the end of the day, you're using
SetThreadpoolTimer
whether you like it or not.
The
CreateTimerQueueTimer
function is just a compatibility function for programs written
to the old thread pool API.
The customer thanked us for the explanation and decided to go with
SetThreadpoolTimer.
