Stack Overflow hook

I have a task “LCD” created like that:
** xTaskCreate( vLCDTask, ( signed portCHAR * ) “LCD”, configMINIMAL_STACK_SIZE, NULL, tskIDLE_PRIORITY, NULL );**

Suppose I want to prevent it from stack overflow. Do I understand correctly that I have to make appropriate changes in FreeRtosConfig, and run function:
vApplicationStackOverflowHook( xTaskHandle *pxTask, signed portCHAR *pcTaskName )
                 …. something…
If yes, what I have to use as parameters? 

**vApplicationStackOverflowHook( vLCDTask, “LCD” **)  ???  I’m in doubt.

If you define the appropriate entries to turn on stack checking, then YOU define vApplicationStackOverflowHook, and FreeRTOS will call it when it detects a stack overflow. Typically the Hook will either just loop so you can check what happened in a debugger, or prints out an error message and reboot your system. It will call the hook function with the parameters of the task that overflowed its stack.
