ustrtok_r
Reentrant function to retrieve tokens from a string.
Description
char *ustrtok_r(char *s,
const char *set,
char **last
);
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'\n", word);
word = ustrtok_r(NULL, " -", &last);
}
free(temp);
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.
