Typedef Documentation

coap_event_handler_t

typedef int(* coap_event_handler_t) (struct coap_context_t *, coap_event_t event, struct coap_session_t *session)

Type for event handler functions that can be registered with a CoAP context using the unction coap_set_event_handler().

When called by the library, the first argument will be the coap_context_t object where the handler function has been registered. The second argument is the event type that may be complemented by event-specific data passed as the third argument.

Definition at line 60 of file coap_event.h.

coap_event_t

typedef unsigned int coap_event_t

Scalar type to represent different events, e.g.

DTLS events or retransmission timeouts.

Definition at line 28 of file coap_event.h.

Function Documentation

coap_clear_event_handler()

COAP_DEPRECATED void coap_clear_event_handler

(

struct coap_context_t *

context

)

Clears the event handler registered with context.

Deprecated:

Use coap_register_event_handler() instead with NULL for hnd.

Parameters

context

The CoAP context whose event handler is to be removed.

Definition at line 30 of file coap_event.c.

coap_register_event_handler()

void coap_register_event_handler	(	struct coap_context_t *	context,
		coap_event_handler_t	hnd
	)

Registers the function hnd as callback for events from the given CoAP context context.

Any event handler that has previously been registered with context will be overwritten by this operation.

Parameters

context	The CoAP context to register the event handler with.
hnd	The event handler to be registered. NULL if to be de-registered.

Definition at line 18 of file coap_event.c.

coap_set_event_handler()

COAP_DEPRECATED void coap_set_event_handler	(	struct coap_context_t *	context,
		coap_event_handler_t	hnd
	)

Registers the function hnd as callback for events from the given CoAP context context.

Any event handler that has previously been registered with context will be overwritten by this operation.

Deprecated:

Use coap_register_event_handler() instead.

Parameters

context	The CoAP context to register the event handler with.
hnd	The event handler to be registered.
