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