[xml] xmlMemUsed() always returns 0 even when mem debug is activated

[apaxeros gmail com]

Hello,

I've been trying to evaluate the amount of memory allocated using xmlMemUsed. A similar question was asked in 2004: http://mail.gnome.org/archives/xml/2004-March/msg00232.html, and Daniel replied that mem debug had to be activated. That's why I recompiled libxml2 (version 2.6.30, on Ubuntu 8.04) with the option --with-mem-debug. Unfortunately, the following code:

 doc = xmlParseFile(argv[2]);
  if (doc == NULL)
  {
      printf ("%s could not be parsed\n", argv[2]);
      exit (1);
  }
  printf("Used memory: %d\n", xmlMemUsed());
  xmlDocDump(stdout, doc);

always returns "Used memory: 0", while xmlDocDump() generates a correct output. Is there a special way of using this function ?

Regards,

Felip.
