Function Documentation

_Rate_monotonic_Allocate()

RTEMS_INLINE_ROUTINE Rate_monotonic_Control * _Rate_monotonic_Allocate

(

void

)

Allocates a period control block from the inactive chain of free period control blocks.

This function allocates a period control block from the inactive chain of free period control blocks.

_Rate_monotonic_Get_status()

bool _Rate_monotonic_Get_status	(	const Rate_monotonic_Control *	the_period,
		Timestamp_Control *	wall_since_last_period,
		Timestamp_Control *	cpu_since_last_period
	)

_Rate_monotonic_Get_status(

This routine is invoked to compute the elapsed wall time and cpu time for a period.

Parameters

[in]	the_period	points to the period being operated upon.
[out]	wall_since_last_period	is set to the wall time elapsed since the period was initiated.
[out]	cpu_since_last_period	is set to the cpu time used by the owning thread since the period was initiated.

Return values

This	routine returns true if the status can be determined and false otherwise.
