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;
while ((option = coap_option_next(&opt_iter))) {
... do something with option ...
coap_opt_t * coap_option_next(coap_opt_iterator_t *oi)
Updates the iterator oi to point to the next option.
Definition: option.c:148
#define COAP_OPT_ALL
Pre-defined filter that includes all options.
Definition: option.h:107
coap_opt_iterator_t * coap_option_iterator_init(const coap_pdu_t *pdu, coap_opt_iterator_t *oi, const coap_opt_filter_t *filter)
Initializes the given option iterator oi to point to the beginning of the pdu's option list.
