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'
", 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.
