NAME
       ustrtok_r  - Reentrant function to retrieve tokens from a string. Alle‐
       gro 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.
