* configGENERATE_RUN_TIME_STATS must be defined as 1 for this function
* to be available. The application must also then provide definitions
* for portCONFIGURE_TIMER_FOR_RUN_TIME_STATS() and
* portGET_RUN_TIME_COUNTER_VALUE to configure a peripheral timer/counter
* and return the timers current count value respectively. A 1uS timer
* frequency is recommended for a 32bit peripheral counter - this will
* allow the statistics to be gathered over the first (approximately) 70
* minutes of execution.
*
* NOTE: This function will disable interrupts for its duration. It is
* not intended for normal application runtime use but as a debug aid.
*
* Setting configGENERATE_RUN_TIME_STATS to 1 will result in a total
* accumulated execution time being stored for each task. The resolution
* of the accumulated time value depends on the frequency of the timer
* configured by the portCONFIGURE_TIMER_FOR_RUN_TIME_STATS() macro.
* Calling vTaskGetRunTimeStats() writes the total execution time of each
* task into a buffer, both as an absolute count value and as a percentage
* of the total system execution time.
*
* @param pcWriteBuffer A buffer into which the execution times will be
* written, in ascii form. This buffer is assumed to be large enough to
* contain the generated report. Approximately 40 bytes per task should
* be sufficient.
