1. For API SetWaitableTimer, what are the meaning and function of
parameters pDueTime and lPeriod?

The timer can be set to fire once at a certain time (or after a certain
time interval), and then repeatedly every X milliseconds after that.
pDueTime determines when the initial one-shot activation occurs. Once it
occurs, lPeriod determines when and whether subsequent periodic
activation should happen.

2. For API CreateWaitableTimer, what is the function and meaning of
parameter bManualReset (what is the different between setting it to
true and setting it to false)?

Manual reset handle, once signalled, remains signalled until reset with
SetWaitableTimer. Automatic reset handle resets to non-signalled state
as soon as a thread successfully finishes a wait on it.
With best wishes,

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
