- The tasks defined on this page demonstrate the use of recursive mutexes.
-
- For recursive mutex functionality the created mutex should be created using
- xSemaphoreCreateRecursiveMutex(), then be manipulated
- using the xSemaphoreTakeRecursive() and xSemaphoreGiveRecursive() API
- functions.
-
- This demo creates three tasks all of which access the same recursive mutex:
-
- prvRecursiveMutexControllingTask() has the highest priority so executes
- first and grabs the mutex. It then performs some recursive accesses -
- between each of which it sleeps for a short period to let the lower
- priority tasks execute. When it has completed its demo functionality
- it gives the mutex back before suspending itself.
-
- prvRecursiveMutexBlockingTask() attempts to access the mutex by performing
- a blocking 'take'. The blocking task has a lower priority than the
- controlling task so by the time it executes the mutex has already been
- taken by the controlling task, causing the blocking task to block. It
- does not unblock until the controlling task has given the mutex back,
- and it does not actually run until the controlling task has suspended
- itself (due to the relative priorities). When it eventually does obtain
- the mutex all it does is give the mutex back prior to also suspending
- itself. At this point both the controlling task and the blocking task are
- suspended.
-
- prvRecursiveMutexPollingTask() runs at the idle priority. It spins round
- a tight loop attempting to obtain the mutex with a non-blocking call. As
- the lowest priority task it will not successfully obtain the mutex until
- both the controlling and blocking tasks are suspended. Once it eventually
- does obtain the mutex it first unsuspends both the controlling task and
- blocking task prior to giving the mutex back - resulting in the polling
- task temporarily inheriting the controlling tasks priority.
