When COAP_PRINT_STATUS_ERROR is set, an error occurred during output. In this case, the other bits are undefined. COAP_PRINT_STATUS_TRUNC indicates that the output is truncated, i.e. the printing would have exceeded the current buffer.

◆ coap_add_attr()

coap_attr_t* coap_add_attr	(	coap_resource_t *	resource,
		coap_str_const_t *	name,
		coap_str_const_t *	value,
		int	flags
	)

Registers a new attribute with the given resource.

As the attribute's coap_str_const_ fields will point to name and value the caller must ensure that these pointers are valid during the attribute's lifetime.

If the name and/or value string is going to be freed off at attribute removal time by the setting of COAP_ATTR_FLAGS_RELEASE_NAME or COAP_ATTR_FLAGS_RELEASE_VALUE in flags, then either the 's' variable of coap_str_const_t has to point to constant text, or point to data within the allocated coap_str_const_t parameter.

Parameters

resource	The resource to register the attribute with.
name	The attribute's name as a string.
value	The attribute's value as a string or `NULL` if none.
flags	Flags for memory management (in particular release of memory). Possible values: COAP_ATTR_FLAGS_RELEASE_NAME If this flag is set, the name passed to coap_add_attr_release() is free'd when the attribute is deleted COAP_ATTR_FLAGS_RELEASE_VALUE If this flag is set, the value passed to coap_add_attr_release() is free'd when the attribute is deleted

Returns: A pointer to the new attribute or NULL on error.

coap_print_status_t coap_print_link	(	const coap_resource_t *	resource,
		unsigned char *	buf,
		size_t *	len,
		size_t *	offset
	)

Writes a description of this resource in link-format to given text buffer.

len must be initialized to the maximum length of buf and will be set to the number of characters actually written if successful. This function returns 1 on success or 0 on error.

Parameters

resource	The resource to describe.
buf	The output buffer to write the description to.
len	Must be initialized to the length of `buf` and will be set to the length of the printed link description.
offset	The offset within the resource description where to start writing into `buf`. This is useful for dealing with the Block2 option. `offset` is updated during output as it is consumed.

Returns: If COAP_PRINT_STATUS_ERROR is set, an error occured. Otherwise, the lower 28 bits will indicate the number of characters that have actually been output into buffer. The flag COAP_PRINT_STATUS_TRUNC indicates that the output has been truncated.

Parameters

context	The context with the resource map.
buf	The buffer to write the result.
buflen	Must be initialized to the maximum length of `buf` and will be set to the length of the well-known response on return.

This function returns the new coap_resource_t object.

If the string is going to be freed off by coap_delete_resource() when COAP_RESOURCE_FLAGS_RELEASE_URI is set in flags, then either the 's' variable of coap_str_const_t has to point to constant text, or point to data within the allocated coap_str_const_t parameter.

COAP_RESOURCE_FLAGS_NOTIFY_CON If this flag is set, coap-observe notifications will be sent confirmable by default.
COAP_RESOURCE_FLAGS_NOTIFY_NON (default) If this flag is set, coap-observe notifications will be sent non-confirmable by default.
If flags is set to 0 then the COAP_RESOURCE_FLAGS_NOTIFY_NON is considered.

Returns: A pointer to the new object or NULL on error.

◆ coap_resource_set_get_observable()

COAP_STATIC_INLINE void coap_resource_set_get_observable	(	coap_resource_t *	resource,
		int	mode
	)

Set whether a resource is observable.

If the resource is observable and the client has set the COAP_OPTION_OBSERVE in a request packet, then whenever the state of the resource changes (a call to coap_resource_trigger_observe()), an Observer response will get sent.

Parameters

resource	The CoAP resource to use.
mode	`1` if Observable is to be set, `0` otherwise.

Here is the call graph for this function:

◆ coap_resource_set_mode()

COAP_STATIC_INLINE void coap_resource_set_mode	(	coap_resource_t *	resource,
		int	mode
	)

Sets the notification message type of resource resource to given mode.

Parameters

resource	The resource to update.
mode	Must be one of `COAP_RESOURCE_FLAGS_NOTIFY_NON` or `COAP_RESOURCE_FLAGS_NOTIFY_CON`.

Definition at line 184 of file resource.h.

◆ coap_resource_set_userdata()

COAP_STATIC_INLINE void coap_resource_set_userdata	(	coap_resource_t *	r,
		void *	data
	)

Sets the user_data.

The user_data is exclusively used by the library-user and can be used as context in the handler functions.

Parameters

r	Resource to attach the data to
data	Data to attach to the user_data field. This pointer is only used for storage, the data remains under user control

Definition at line 199 of file resource.h.

◆ coap_resource_unknown_init()

coap_resource_t* coap_resource_unknown_init ( coap_method_handler_t put_handler )

Creates a new resource object for the unknown resource handler with support for PUT.

In the same way that additional handlers can be added to the resource created by coap_resource_init() by using coap_register_handler(), POST, GET, DELETE etc. handlers can be added to this resource. It is the responsibility of the application to manage the unknown resources by either creating new resources with coap_resource_init() (which should have a DELETE handler specified for the resource removal) or by maintaining an active resource list.

Note: There can only be one unknown resource handler per context - attaching a new one overrides the previous definition.

Note: It is not possible to observe the unknown resource with a GET request

a separate resource needs to be reated by the PUT (or POST) handler, and make that resource observable.

This function returns the new coap_resource_t object.

Parameters

put_handler The PUT handler to register with resource for unknown Uri-Path.

Returns: A pointer to the new object or NULL on error.
