Task control block.

Mar 25, 2014 · FreeRTOS allocates memory for the task’s control block (TCB) structure ( tskTCB type in tasks.c ), followed by memory for its stack, when your code calls xTaskCreate to create a new task. To find the TCB of the currently executing task look at pxCurrentTCB in tasks.c. A color coded view of how the tskTCB structure looks in memory follows.
