void vApplicationIdleHook

(

void vApplicationMallocFailedHook

(

void

)

vApplicationMallocFailedHook() will only be called if configUSE_MALLOC_FAILED_HOOK is set to 1 in FreeRTOSConfig.h. It is a hook function that will get called if a call to pvPortMalloc() fails. pvPortMalloc() is called internally by the kernel whenever a task, queue, timer or semaphore is created. It is also called by various parts of the demo application. If heap_1.c or heap_2.c are used, then the size of the heap available to pvPortMalloc() is defined by configTOTAL_HEAP_SIZE in FreeRTOSConfig.h, and the xPortGetFreeHeapSize() API function can be used to query the size of free heap space that remains (although it does not provide information on how the remaining heap might be fragmented).

void vApplicationStackOverflowHook	(	xTaskHandle	pxTask,
		signed char *	pcTaskName
	)

Run time stack overflow checking is performed if configCHECK_FOR_STACK_OVERFLOW is defined to 1 or 2. This hook function is called if a stack overflow is detected.

void vApplicationTickHook

(

void

)

This function is called by FreeRTOS each tick.

This function will be called by each tick interrupt if configUSE_TICK_HOOK is set to 1 in FreeRTOSConfig.h. User code can be added here, but the tick hook is called from an interrupt context, so code must not attempt to block, and only the interrupt safe FreeRTOS API functions can be used (those that end in FromISR()).
