ustrtok - Retrieves tokens from a string. Allegro game programming library.

       This  function  retrieves  tokens  from `s' which are delimited by characters from `set'. To initiate the
       search, pass the string to be searched as `s'.  For the remaining tokens,  pass  NULL  instead.  Warning:
       Since  ustrtok  alters  the string it is parsing, you should always copy the string to a temporary buffer
       before parsing it. Also, this function is not re-entrant (ie. you cannot parse two strings  at  the  same
       time). Example:

          char *word;
          char string[]="some-words with dashes";
          char *temp = ustrdup(string);
          word = ustrtok(temp, " -");
          while (word) {
             allegro_message("Found `%s'\n", word);
             word = ustrtok(NULL, " -");
          }
          free(temp);
