I want to print the string "tvb->real_data "which at
packet-http.c:dissect on the ubuntu terminal .But whatever I add
"printf("%s\n",tvb->real_data);"or"printf(stdout,"%s\n",tvb->real_data);" into
the packet-http:dissect_http function ,nothing to be showed on the terminal.

What should I do to display the string "tvb->data"on the terminal?
