APIs Exported by NuttX to Architecture-Specific Logic
=====================================================

These are standard interfaces that are exported by the OS for use
by the architecture specific logic.

OS List Management APIs
=======================

**To be provided**

.. c:function:: void nxsched_process_timer(void)

  This function handles system timer events. The
  timer interrupt logic itself is implemented in the architecture
  specific code, but must call the following OS function
  periodically -- the calling interval must be
  ``CONFIG_USEC_PER_TICK``.

.. c:function:: void irq_dispatch(int irq, FAR void *context)

  This function must be called from the
  architecture- specific logic in order to display an interrupt to
  the appropriate, registered handling logic.
