Function esp_idf_svc::hal::sys::xTaskResumeAll

pub unsafe extern "C" fn xTaskResumeAll() -> i32

Resumes scheduler activity after it was suspended by a call to vTaskSuspendAll().

xTaskResumeAll() only resumes the scheduler. It does not unsuspend tasks that were previously suspended by a call to vTaskSuspend().

@return If resuming the scheduler caused a context switch then pdTRUE is returned, otherwise pdFALSE is returned.

Example usage: @code{c} void vTask1( void * pvParameters ) { for( ;; ) { // Task code goes here.

  // ...

  // At some point the task wants to perform a long operation during
  // which it does not want to get swapped out.  It cannot use
  // taskENTER_CRITICAL ()/taskEXIT_CRITICAL () as the length of the
  // operation may cause interrupts to be missed - including the
  // ticks.

  // Prevent the real time kernel swapping out the task.
  vTaskSuspendAll ();

  // Perform the operation here.  There is no need to use critical
  // sections as we have all the microcontroller processing time.
  // During this time interrupts will still operate and the real
  // time kernel tick count will be maintained.

  // ...

  // The operation is complete.  Restart the kernel.  We want to force
  // a context switch - but there is no point if resuming the scheduler
  // caused a context switch already.
  if( !xTaskResumeAll () )
  {
       taskYIELD ();
  }
