ustrtok_r - Reentrant function to retrieve tokens from a string. Allegro game programming library.

       Reentrant  version  of  ustrtok. The `last' parameter is used to keep track of where the parsing is up to
       and must be a pointer to a char * variable allocated by the user that remains the same while parsing  the
       same string. Example:

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

       ustrtok_r - Reentrant function to retrieve tokens from a string. Allegro game programming library.

       Returns  a  pointer  to  the  token,  or NULL if no more are found. You can free the memory pointed to by
       `last' once NULL is returned.
