SYNOPSIS

10       #include <allegro.h>

13       char *ustrtok_r(char *s, const char *set, char **last);

DESCRIPTION

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);

RETURN VALUE

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.
