The CoAP stack's global state is stored in a coap_context_t object.

Fields

known_options: coap_opt_filter_tresources: *mut coap_resource_t

< hash table or list of known resources

unknown_resource: *mut coap_resource_t

< can be used for handling unknown resources

async_state: *mut coap_async_state_t

list of asynchronous transactions

sendqueue_basetime: coap_tick_t

The time stamp in the first element of the sendqeue is relative to sendqueue_basetime.

sendqueue: *mut coap_queue_tendpoint: *mut coap_endpoint_t

< the endpoints used for listening
