Detailed Description

CoAP Header parser.

Functionality: Parses CoAP Header

Definition in file sn_coap_parser.c.

Function Documentation

Parses CoAP message from given Packet data.

Parameters:

*handle	Pointer to CoAP library handle
packet_data_len	is length of given Packet data to be parsed to CoAP message
*packet_data_ptr	is source for Packet data to be parsed to CoAP message
*coap_version_ptr	is destination for parsed CoAP specification version

Returns:: Return value is pointer to parsed CoAP message.
In following failure cases NULL is returned:
-Failure in given pointer (= NULL)
-Failure in memory allocation (malloc() returns NULL)

		uint8_t *	packet_data_ptr,
		uint8_t **	packet_data_pptr,
		sn_coap_hdr_s *	dst_coap_msg_ptr
	)		`[static]`

Parses CoAP message's Payload part from given Packet data.

Parameters:

packet_data_len	is length of given Packet data to be parsed to CoAP message
*packet_data_ptr	is start of source for Packet data to be parsed to CoAP message
**packet_data_pptr	is source for Packet data to be parsed to CoAP message

void sn_coap_parser_release_allocated_coap_msg_mem	(	struct coap_s *	handle,
		sn_coap_hdr_s *	freed_coap_msg_ptr
	)

Releases memory of given CoAP message.

Note!!! Does not release Payload part

Parameters:

*handle	Pointer to CoAP library handle
*freed_coap_msg_ptr	is pointer to released CoAP message
