ustrtok3alleg4

Usage

Overview

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.
