Notes/Warnings

• Execution time of this task depends on the size of the task’s stack.
• The application can determine the total task stack space (in number of CPU_STK elements) by adding the value of *p_free and *p_used. This number should add up to the task’s stack size which is stored in the .StkSize field of the OS_TCB of the task.
• The #define CPU_CFG_STK_GROWTH must be declared (typically from os_cpu.h). When this #define is set to CPU_STK_GROWTH_LO_TO_HI, the stack grows from low memory to high memory. When this #define is set to CPU_STK_GROWTH_HI_TO_LO, the stack grows from high memory to low memory.
