Only a single on_exit function can be registered unless + * CONFIG_LIBC_MAX_EXITFUNS defines a larger number. + * 2. on_exit functions are not inherited when a new task is + * created. + * + * Input Parameters: + * func - A pointer to the function to be called when the task exits. + * arg - An argument that will be provided to the on_exit() function when + * the task exits. + * + * Returned Value: + * Zero on success.
