Re: Re: [lwip-users] Struggling to build a TCP echo server

[Chen]

Maybe I missed something, but all I need to kill my working
echo server is to add this line (in the same thread)

lSocket2 = socket(AF_INET,
SOCK_STREAM, 0);

So that my code turns into this:

int lSocket;
int lSocket2;
struct sockaddr_in sLocalAddr;

lSocket = socket(AF_INET, SOCK_STREAM, 0);
lSocket2 = socket(AF_INET,
SOCK_STREAM, 0);

....
