38 * Start the kernel monitor. It is a special process which checks every second the stacks of the
39 * running processes trying to detect stack overflows.
41 * \param stacksize Size of stack in chars
42 * \param stack Pointer to the stack that will be used by the monitor
44 * \note The stack is provided by the caller so that there is no wasted space if the monitor
47 void monitor_start(size_t stacksize, cpustack_t *stack);
51 * Manually check if a given stack has overflown. This is used to check for stacks
52 * of processes handled externally form the kernel, or for other stacks (for instance
53 * the interrupt supervisor stack).
55 * \note For this function to work, the stack must have been filled at startup with
56 * CONFIG_KERN_STACKFILLCODE.
