Detailed Description
CoAP Protocol implementation.
Functionality: CoAP Protocol
Definition in file sn_coap_protocol.c.
Function Documentation
| static uint16_t sn_coap_count_linked_list_size | ( | const coap_send_msg_list_t * | linked_list_ptr ) | [static] |
Counts total message size of all messages in linked list.
- Parameters:
-
const coap_send_msg_list_t *linked_list_ptr pointer to linked list
Definition at line 1451 of file sn_coap_protocol.c.
| void sn_coap_protocol_clear_retransmission_buffer | ( | struct coap_s * | handle ) |
If re-transmissions are enabled, this function removes all messages from the retransmission queue.
- Parameters:
-
*handle Pointer to CoAP library handle
Definition at line 294 of file sn_coap_protocol.c.
| int8_t sn_coap_protocol_exec | ( | struct coap_s * | handle, |
| uint32_t | current_time | ||
| ) |
Sends CoAP messages from re-sending queue, if there is any.
Cleans also old messages from the duplication list and from block receiving list
This function can be called e.g. once in a second but also more frequently.
- Parameters:
-
*handle Pointer to CoAP library handle current_time is System time in seconds. This time is used for message re-sending timing and to identify old saved data.
- Returns:
- 0 if success -1 if failed
Definition at line 706 of file sn_coap_protocol.c.
| static void sn_coap_protocol_linked_list_blockwise_msg_remove | ( | struct coap_s * | handle, |
| coap_blockwise_msg_s * | removed_msg_ptr | ||
| ) | [static] |
Removes stored blockwise message from Linked list.
- Parameters:
-
removed_msg_ptr is message to be removed
Definition at line 1113 of file sn_coap_protocol.c.
| static void sn_coap_protocol_linked_list_blockwise_payload_remove_oldest | ( | struct coap_s * | handle ) | [static] |
Removes current stored blockwise paylod from Linked list.
Definition at line 1235 of file sn_coap_protocol.c.
| static void sn_coap_protocol_linked_list_blockwise_remove_old_data | ( | struct coap_s * | handle ) | [static] |
Removes old stored Blockwise messages and payloads from Linked list.
Definition at line 1310 of file sn_coap_protocol.c.
| static void sn_coap_protocol_linked_list_duplication_info_remove | ( | struct coap_s * | handle, |
| uint8_t * | addr_ptr, | ||
| uint16_t | port, | ||
| uint16_t | msg_id | ||
| ) | [static] |
Removes stored Duplication info from Linked list.
- Parameters:
-
*addr_ptr is pointer to Address key to be removed port is Port key to be removed msg_id is Message ID key to be removed
Definition at line 1051 of file sn_coap_protocol.c.
| static void sn_coap_protocol_linked_list_duplication_info_remove_old_ones | ( | struct coap_s * | handle ) | [static] |

| static void sn_coap_protocol_release_allocated_send_msg_mem | ( | struct coap_s * | handle, |
| coap_send_msg_s * | freed_send_msg_ptr | ||
| ) | [static] |
Releases memory of given Sending message (coap_send_msg_s)
- Parameters:
-
*freed_send_msg_ptr is pointer to released Sending message
Definition at line 1411 of file sn_coap_protocol.c.
