ustrtok_r(3)                    Allegro manual                    ustrtok_r(3)



NAME
       ustrtok_r - Reentrant function to retrieve tokens from a string.
       Allegro game programming library.

SYNOPSIS
       #include <allegro.h>


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

DESCRIPTION
       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);

RETURN VALUE
       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.
