TSContScheduleEveryOnPool
*************************

Synopsis
========

.. code-block:: cpp

    #include <ts/ts.h>

.. function:: TSAction TSContScheduleEveryOnPool(TSCont contp, TSHRTime every)

Description
===========

Schedules :arg:`contp` to run :arg:`every` milliseconds, on a random thread that belongs to
:arg:`tp`. The :arg:`every` is an approximation, meaning it will be at least :arg:`every`
milliseconds but possibly more. Resolutions finer than roughly 5 milliseconds will not be
effective. Note that :arg:`contp` is required to have a mutex, which is provided to
:func:`TSContCreate`.

The return value can be used to cancel the scheduled event via :func:`TSActionCancel`. This
is effective until the continuation :arg:`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 :func:`TSActionDone` to see if the continuation ran before the return,
which is possible if :arg:`timeout` is `0`.

If :arg:`contp` has no thread affinity set, the thread it is now scheduled on will be set
as its thread affinity thread.

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.
