unsigned portBASE_TYPE uxTaskGetStackHighWaterMark( xTaskHandle xTask );
INCLUDE_uxTaskGetStackHighWaterMark must be set to 1 in FreeRTOSConfig.h for this function to be available.
Returns the high water mark of the stack associated with xTask. That is, the minimum free stack space there has been (in words, so on a 32 bit machine a value of 1 means 4 bytes) since the task started. The smaller the returned number the closer the task has come to overflowing its stack.
- Parameters
-
xTask | Handle of the task associated with the stack to be checked. Set xTask to NULL to check the stack of the calling task. |
- Returns
- The smallest amount of free stack space there has been (in bytes) since the task referenced by xTask was created.
