------------------------------+-----------------------------
Mapping task priorities to/from POSIX thread priorities is probably done
in many applications. There seems to be no API to help doing this. Add the
following API functions to map a task priority to/from a POSIX thread
priority:
{{{
#!c
/**
* @brief Map a task priority to the corresonding POSIX thread priority.
*
* @param scheduler_id Identifier of the scheduler instance.
* @param priority The task priority to map.
* @param[out] posix_priority Pointer to a POSIX thread priority value.
*
* @retval RTEMS_SUCCESSFUL Successful operation.
* @retval RTEMS_INVALID_ADDRESS The @a posix_priority parameter is @c
NULL.
* @retval RTEMS_INVALID_ID Invalid scheduler instance identifier.
* @retval RTEMS_INVALID_PRIORITY Invalid task priority.
*/
rtems_status_code rtems_scheduler_map_to_posix_priority(
rtems_id scheduler_id,
rtems_task_priority priority,
int *posix_priority
);
/**
