## Data Structures

struct | coap_subscription_t
| Number of notifications that may be sent non-confirmable before a confirmable message is sent to detect if observers are alive. More...

## Functions

void | coap_subscription_init (coap_subscription_t *)
void | coap_handle_failed_notify (coap_context_t *context, coap_session_t *session, const coap_bin_const_t *token)
| Handles a failed observe notify.
coap_subscription_t * | coap_add_observer (coap_resource_t *resource, coap_session_t *session, const coap_bin_const_t *token, const coap_pdu_t *pdu)
| Adds the specified peer as observer for `resource`.
coap_subscription_t * | coap_find_observer (coap_resource_t *resource, coap_session_t *session, const coap_bin_const_t *token)
| Returns a subscription object for given `peer`.
void | coap_touch_observer (coap_context_t *context, coap_session_t *session, const coap_bin_const_t *token)
| Flags that data is ready to be sent to observers.
int | coap_delete_observer (coap_resource_t *resource, coap_session_t *session, const coap_bin_const_t *token)
| Removes any subscription for `session` observer from `resource` and releases the allocated storage.
int | coap_delete_observer_request (coap_resource_t *resource, coap_session_t *session, const coap_bin_const_t *token, coap_pdu_t *request)
| Removes any subscription for `session` observer from `resource` and releases the allocated storage.
void | coap_delete_observers (coap_context_t *context, coap_session_t *session)
| Removes any subscription for `session` and releases the allocated storage.
int | coap_resource_notify_observers_lkd (coap_resource_t *resource, const coap_string_t *query)
| Initiate the sending of an Observe packet for all observers of `resource`, optionally matching `query` if not NULL.
void | coap_check_notify_lkd (coap_context_t *context)
| Checks all known resources to see if they are dirty and then notifies subscribed observers.
void | coap_persist_cleanup (coap_context_t *context)
| Close down persist tracking, releasing any memory used.
coap_subscription_t * | coap_persist_observe_add_lkd (coap_context_t *context, coap_proto_t e_proto, const coap_address_t *e_listen_addr, const coap_addr_tuple_t *s_addr_info, const coap_bin_const_t *raw_packet, const coap_bin_const_t *oscore_info)
| Set up an active subscription for an observe that was previously active over a coap-server inadvertant restart.
int | coap_persist_startup_lkd (coap_context_t *context, const char *dyn_resource_save_file, const char *observe_save_file, const char *obs_cnt_save_file, uint32_t save_freq)
| Start up persist tracking using the libcoap module.
void | coap_persist_stop_lkd (coap_context_t *context)
| Stop tracking persist information, leaving the current persist information in the files defined in coap_persist_startup().
int | coap_cancel_observe_lkd (coap_session_t *session, coap_binary_t *token, coap_pdu_type_t message_type)
| Cancel an observe that is being tracked by the client large receive logic.
