Hello!!
I have been studying how to make a linger close of a socket in lwip. First
of all, I have used the standard lwip_close() function as it is, an I have
noticed that it gets stucked in the "netconn_delete(sock->conn);"
statement. I suppose that here it will wait for the closure handshake to
get completed or something like that.
Later, I tried to see how to use the SO_LINGER option. And I saw that this
option is listed in sockets.h but I cannot find it in sockets.c. I had a
look in lwip_setsockopt(), but I did not find the SO_LINGER definition. In
addition, I saw that many other options are unimplemented. Then, my
question is: Can a linger close be implemented under lwip?? How?? Usingo
the SO_LINGER option in setsockopt ???
Thank you very much for your helpful advice.
Regards,
Borja.
