14
16 Reentrant version of ustrtok. The `last' parameter is used to keep
17 track of where the parsing is up to and must be a pointer to a char *
18 variable allocated by the user that remains the same while parsing the
19 same string. Example:
20
21 char *word, *last;
22 char string[]="some-words with dashes";
23 char *temp = ustrdup(string);
24 word = ustrtok_r(string, " -", &last);
25 while (word) {
26 allegro_message("Found `%s'\n", word);
27 word = ustrtok_r(NULL, " -", &last);
28 }
29 free(temp);
30
32 Returns a pointer to the token, or NULL if no more are found. You can
33 free the memory pointed to by `last' once NULL is returned.
