Detailed Description

Iterator to run through PDU options.

This object must be initialized with coap_option_iterator_init(). Call coap_option_next() to walk through the list of options until coap_option_next() returns NULL.

coap_opt_t *option;
coap_opt_iterator_t opt_iter;
coap_option_iterator_init(pdu, &opt_iter, COAP_OPT_ALL);
 
while ((option = coap_option_next(&opt_iter))) {
  ... do something with option ...
}
