NAME

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

SYNOPSIS

       #include <allegro.h>

       char *ustrtok_r(char *s, const char *set, char **last);

DESCRIPTION

       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);

RETURN VALUE

       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.
