It has the format of: __print_array(__get_dynamic_array(array), __get_dynmaic_array_len(array) / el_size, el_size) Since dynamic arrays are known to the tracing infrastructure, create a helper macro that does the above for you. __print_dynamic_array(array, el_size) Which would expand to the same output.
