[lwip-users] [lwip] Q: tcp_connect()

[Aleksander Wysocki]

hi!

looking at this function from "raw api"
i'm a bit confused, because we pass a pcb into it,
and callback function (* connected) , 
gives us also a pcb. 
it seems, that having (void * arg) we can recognize the context
of this callback and associate the proper pcb.
is this redundant, isn't it?
and if not, then why?

(and yes! i understand, it could be an old obsolete parameter in interface,
but i want to be sure (for the future :-)

Olek
