+ * p_free() on it.
+ *
+ * The common usage of this call is following:
+ * @code
+ * pchar *token, *buf;
+ * pchar str[] = "This is a test string"
+ * pchar delim[] = " \t"
+ * ...
+ * token = p_strtok (str, delim, &buf);

+ *     printf ("Splitted string: %s\n", token);
+ *     token = p_strtok (NULL, delim, &buf);
+ * }
+ * @endcode
+ * Take attention that you need to pass the original string only once, after
+ * that you should pass NULL instead. You can also pass different delimiters
+ * each time.
+ *
+ * Some platforms do not support the third parameter and it can be remained
+ * unused. In that case this call wouldn't be thread-safe.
