TSContScheduleEveryOnThread
***************************

Synopsis
========

.. code-block:: cpp

    #include <ts/ts.h>

.. function:: TSAction TSContScheduleEveryOnThread(TSCont contp, TSHRTime every, TSEventThread ethread)

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

Schedules :arg:`contp` to run :arg:`every` milliseconds, on the thread specified by
:arg:`ethread`. 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.

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.
