Schedules contp to run delay milliseconds in the future. This is approximate. The delay
will be at least delay but possibly more. Resolutions finer than roughly 5 milliseconds will
not be effective. contp is required to have a mutex, which is provided to
The return value can be used to cancel the scheduled event via
TSActionCancel(). This is
effective until the continuation contp is being dispatched. However, if it is scheduled on
another thread this can be problematic to be correctly timed. The return value can be checked with
TSActionDone() to see if the continuation ran before the return, which is possible if
timeout is 0. Returns
nullptr if thread affinity was cleared.
TSContSchedule() or TSContScheduleEvery() will default to set the thread affinity to the calling thread
when no affinity is already set for example, using
Note that the TSContSchedule() family of API shall only be called from an ATS EThread. Calling it from raw non-EThreads can result in unpredictable behavior.
