ustrtok(3)                      Allegro manual                      ustrtok(3)



NAME
       ustrtok - Retrieves tokens from a string. Allegro game programming
       library.

SYNOPSIS
       #include <allegro.h>


       char *ustrtok(char *s, const char *set);

DESCRIPTION
       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.
