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.

void nxsched_timer_expiration(void)

Description: if CONFIG_SCHED_TICKLESS is defined, then this function is provided by the RTOS base code and called from platform-specific code when the interval timer used to implemented the tick-less OS expires.

Assumptions: Base code implementation assumes that this function is called from interrupt handling logic with interrupts disabled.

void nxsched_alarm_expiration(void);

If CONFIG_SCHED_TICKLESS is defined, then this function is provided by the RTOS base code and called from platform-specific code when the interval timer used to implemented the tick-less OS expires.

Assumptions: Base code implementation assumes that this function is called from interrupt handling logic with interrupts disabled.

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.
