Find the current process index: vlib_node_main_t *nm = &vm->node_main; current_process_index = nm->current_process_index;
Find the process object: vlib_process_t *p = vec_elt (nm->processes, current_process_index); Find the stack base: p->stack Take the address of a local variable in a function at what you think is the maximum stack depth, and subtract. That’s the instantaneous stack depth. You can sprinkle “stack_depth_now = p->stack - &foo; if (stack_depth_now > max_stack_depth) max = now” cookies in various places. HTH...

We are creating a process node, how to figure out the value of process_log2_n_stack_bytes?? Thanks,
