Functions
coap_lg_xmit_t *	coap_find_lg_xmit (coap_session_t session, coap_pdu_t pdu)
	Find the current lg_xmit for the session that matches the pdu.

void	coap_block_delete_lg_xmit (coap_session_t session, coap_lg_xmit_t lg_xmit)

int	coap_block_check_lg_xmit_timeouts (coap_session_t session, coap_tick_t now, coap_tick_t tim_rem)

void	coap_check_code_lg_xmit (const coap_session_t session, const coap_pdu_t request, coap_pdu_t response, const coap_resource_t resource, const coap_string_t *query)
	The function checks that the code in a newly formed lg_xmit created by coap_add_data_large_response_lkd() is updated.

void	coap_context_set_block_mode_lkd (coap_context_t *context, uint32_t block_mode)
	Set the context level CoAP block handling bits for handling RFC7959.

int	coap_context_set_max_block_size_lkd (coap_context_t *context, size_t max_block_size)
	Set the context level maximum block size that the server supports when sending or receiving packets with Block1 or Block2 options.

coap_binary_t *	coap_block_build_body_lkd (coap_binary_t body_data, size_t length, const uint8_t data, size_t offset, size_t total)
	Re-assemble payloads into a body.
