Yes, please.  Here is a snippet from GnuPG which does this.  I grant you
the right to use this under "GPLv2+ with exception for Mozilla" as used
by Scute.

  else if (keywordlen == 6 && !memcmp (keyword, "EXTCAP", keywordlen))
    {
      char *p, *p2, *buf;
      int abool;

      buf = p = unescape_status_string (line);
      if (buf)
        {
          for (p = strtok (buf, " "); p; p = strtok (NULL, " "))
            {
              p2 = strchr (p, '=');
              if (p2)
                {
                  *p2++ = 0;
                  abool = (*p2 == '1');
                  if (!strcmp (p, "ki"))
                    parm->extcap.ki = abool;
                  else if (!strcmp (p, "aac"))
                    parm->extcap.aac = abool;
                  else if (!strcmp (p, "si"))
                    parm->status_indicator = strtoul (p2, NULL, 10);
                }
            }
          xfree (buf);
        }
    }
