eTaskState eTaskGetState( TaskHandle_t xTask );

INCLUDE_eTaskGetState must be defined as 1 for this function to be available. See the configuration section for more information.

Obtain the state of any task. States are encoded by the eTaskState enumerated type.

Parameters

xTask

Handle of the task to be queried.

Returns

The state of xTask at the time the function was called. Note the state of the task might change between the function being called, and the functions return value being tested by the calling task.

task.h

UBaseType_t uxTaskGetStackHighWaterMark( TaskHandle_t 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 words, so actual spaces on the stack rather than bytes) since the task referenced by xTask was created.

UBaseType_t uxTaskGetSystemState	(	TaskStatus_t *const	pxTaskStatusArray,
		const UBaseType_t	uxArraySize,
		uint32_t *const	pulTotalRunTime
	)

configUSE_TRACE_FACILITY must be defined as 1 in FreeRTOSConfig.h for uxTaskGetSystemState() to be available.

uxTaskGetSystemState() populates an TaskStatus_t structure for each task in the system. TaskStatus_t structures contain, among other things, members for the task handle, task name, task priority, task state, and total amount of run time consumed by the task. See the TaskStatus_t structure definition in this file for the full member list.

NOTE: This function is intended for debugging use only as its use results in the scheduler remaining suspended for an extended period.

Parameters

pxTaskStatusArray	A pointer to an array of TaskStatus_t structures. The array must contain at least one TaskStatus_t structure for each task that is under the control of the RTOS. The number of tasks under the control of the RTOS can be determined using the uxTaskGetNumberOfTasks() API function.
uxArraySize	The size of the array pointed to by the pxTaskStatusArray parameter. The size is specified as the number of indexes in the array, or the number of TaskStatus_t structures contained in the array, not by the number of bytes in the array.
pulTotalRunTime	If configGENERATE_RUN_TIME_STATS is set to 1 in FreeRTOSConfig.h then *pulTotalRunTime is set by uxTaskGetSystemState() to the total run time (as defined by the run time stats clock, see http://www.freertos.org/rtos-run-time-stats.html) since the target booted. pulTotalRunTime can be set to NULL to omit the total run time information.

Returns

The number of TaskStatus_t structures that were populated by uxTaskGetSystemState(). This should equal the number returned by the uxTaskGetNumberOfTasks() API function, but will be zero if the value passed in the uxArraySize parameter was too small.

Example usage:

This example demonstrates how a human readable table of run time stats
information is generated from raw data provided by uxTaskGetSystemState().
The human readable table is written to pcWriteBuffer
    void vTaskGetRunTimeStats( char *pcWriteBuffer )
    {
    TaskStatus_t *pxTaskStatusArray;
    volatile UBaseType_t uxArraySize, x;
    uint32_t ulTotalRunTime, ulStatsAsPercentage;

Make sure the write buffer does not contain a string.
         pcWriteBuffer = 0x00;

Take a snapshot of the number of tasks in case it changes while this
function is executing.
        uxArraySize = uxTaskGetNumberOfTasks();

Allocate a TaskStatus_t structure for each task.  An array could be
allocated statically at compile time.
        pxTaskStatusArray = pvPortMalloc( uxArraySize * sizeof( TaskStatus_t ) );

        if( pxTaskStatusArray != NULL )
        {
Generate raw status information about each task.
            uxArraySize = uxTaskGetSystemState( pxTaskStatusArray, uxArraySize, &ulTotalRunTime );

For percentage calculations.
            ulTotalRunTime /= 100UL;

Avoid divide by zero errors.
            if( ulTotalRunTime > 0 )
            {
For each populated position in the pxTaskStatusArray array,
format the raw data as human readable ASCII data
                for( x = 0; x < uxArraySize; x++ )
                {
What percentage of the total run time has the task used?
This will always be rounded down to the nearest integer.
ulTotalRunTimeDiv100 has already been divided by 100.
                    ulStatsAsPercentage = pxTaskStatusArray[ x ].ulRunTimeCounter / ulTotalRunTime;

                    if( ulStatsAsPercentage > 0UL )
                    {
                        sprintf( pcWriteBuffer, "%s\t\t%lu\t\t%lu%%\r\n", pxTaskStatusArray[ x ].pcTaskName, pxTaskStatusArray[ x ].ulRunTimeCounter, ulStatsAsPercentage );
                    }
                    else
                    {
If the percentage is zero here then the task has
consumed less than 1% of the total run time.
                        sprintf( pcWriteBuffer, "%s\t\t%lu\t\t<1%%\r\n", pxTaskStatusArray[ x ].pcTaskName, pxTaskStatusArray[ x ].ulRunTimeCounter );
                    }

                    pcWriteBuffer += strlen( ( char * ) pcWriteBuffer );
                }
            }

The array is no longer needed, free the memory it consumes.
            vPortFree( pxTaskStatusArray );
        }
    }
