 void vAFunction( void )
 {
 TaskHandle_t xHandle;

     // Create a task, storing the handle.
     xTaskCreate( vTaskCode, "NAME", STACK_SIZE, NULL, tskIDLE_PRIORITY, &xHandle );

     // ...

     // Use the handle to obtain the priority of the created task.
     // It was created with tskIDLE_PRIORITY, but may have changed
     // it itself.
     if( uxTaskPriorityGet( xHandle ) != tskIDLE_PRIORITY )
     {
         // The task has changed its priority.
     }

     // ...

     // Is our priority higher than the created task?
     if( uxTaskPriorityGet( xHandle ) < uxTaskPriorityGet( NULL ) )
     {
         // Our priority (obtained using NULL handle) is higher.
     }
