#include <api.h>
Data Fields | |
| enum netconn_type | type |
| type of the netconn (TCP, UDP or RAW) | |
| enum netconn_state | state |
| current state of the netconn | |
| err_t | last_err |
| the last error this netconn had | |
| sys_sem_t | op_completed |
| sem that is used to synchroneously execute functions in the core context | |
| sys_mbox_t | recvmbox |
| mbox where received packets are stored until they are fetched by the netconn application thread (can grow quite big) | |
| sys_mbox_t | acceptmbox |
| mbox where new connections are stored until processed by the application thread | |
| int | socket |
| only used for socket layer | |
| int | recv_timeout |
| timeout to wait for new data to be received (or connections to arrive for listening netconns) | |
| int | recv_bufsize |
| maximum amount of bytes queued in recvmbox not used for TCP: adjust TCP_WND instead! | |
| s16_t | recv_avail |
| number of bytes currently in recvmbox to be received, tested against recv_bufsize to limit bytes on recvmbox for UDP and RAW | |
| u8_t | flags |
| flags holding more netconn-internal state, see NETCONN_FLAG_* defines | |
| size_t | write_offset |
| TCP: when data passed to netconn_write doesn't fit into the send buffer, this temporarily stores how much is already sent. | |
| struct api_msg_msg * | current_msg |
| TCP: when data passed to netconn_write doesn't fit into the send buffer, this temporarily stores the message. | |
| netconn_callback | callback |
| A callback function that is informed about events for this netconn. | |
