See the configuration section of the FreeRTOS.org website for more information.</p>

<p>NOTE 1: This function will disable interrupts for its duration. It is not intended for normal application runtime use but as a debug aid.</p>

<p>Lists all the current tasks, along with their current state and stack usage high water mark.</p>

<p>Tasks are reported as blocked ('B'), ready ('R'), deleted ('D') or suspended ('S').</p>

<p>PLEASE NOTE:</p>

<p>This function is provided for convenience only, and is used by many of the demo applications. Do not consider it to be part of the scheduler.</p>

<p><a class="el" href="task_8h.html#ab87abc717f34ddced76802d12588a93d">vTaskList()</a> calls <a class="el" href="task_8h.html#aa4603f3de3d809e9beb18d10fbac005d">uxTaskGetSystemState()</a>, then formats part of the <a class="el" href="task_8h.html#aa4603f3de3d809e9beb18d10fbac005d">uxTaskGetSystemState()</a> output into a human readable table that displays task names, states and stack usage.</p>
|
|
<p><a class="el" href="task_8h.html#ab87abc717f34ddced76802d12588a93d">vTaskList()</a> has a dependency on the sprintf() C library function that might bloat the code size, use a lot of stack, and provide different results on different platforms. An alternative, tiny, third party, and limited functionality implementation of sprintf() is provided in many of the FreeRTOS/Demo sub-directories in a file called printf-stdarg.c (note printf-stdarg.c does not provide a full snprintf() implementation!).</p>
|
|
<p>It is recommended that production systems call <a class="el" href="task_8h.html#aa4603f3de3d809e9beb18d10fbac005d">uxTaskGetSystemState()</a> directly to get access to raw stats data, rather than indirectly through a call to <a class="el" href="task_8h.html#ab87abc717f34ddced76802d12588a93d">vTaskList()</a>.</p>
