NAME

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

SYNOPSIS

       #include <allegro.h>

       char *ustrtok(char *s, const char *set);

DESCRIPTION

       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);

RETURN VALUE

       Returns a pointer to the token, or NULL if no more are found.
