Detailed Description

Contains all internal pointers and states used for a socket

Field Documentation

conn

struct netconn* lwip_sock::conn

sockets currently are built on netconns, each socket has one netconn

err

u8_t lwip_sock::err

last error that occurred on this socket (in fact, all our errnos fit into an u8_t)

errevent

u16_t lwip_sock::errevent

error happened for this socket, set by event_callback(), tested by select

lastdata

void* lwip_sock::lastdata

data that was left from the previous read

lastoffset

u16_t lwip_sock::lastoffset

offset in the data that was left from the previous read

rcvevent

s16_t lwip_sock::rcvevent

number of times data was received, set by event_callback(), tested by the receive and select functions

select_waiting

u8_t lwip_sock::select_waiting

counter of how many threads are waiting for this socket using select

sendevent

u16_t lwip_sock::sendevent

number of times data was ACKed (free send buffer), set by event_callback(), tested by select
