18.3.3: Obtaining a Period's Status

If the rtems_rate_monotonic_period directive is invoked with a period of RTEMS_PERIOD_STATUS ticks, the current state of the specified rate monotonic period will be returned. The following table details the relationship between the period's status and the directive status code returned by the rtems_rate_monotonic_period directive:

RTEMS_SUCCESSFUL - period is running
RTEMS_TIMEOUT - period has expired
RTEMS_NOT_DEFINED - period has never been initiated

Obtaining the status of a rate monotonic period does not alter the state or length of that period.
