[lwip-users] netbuf_data() netconnwrite() problem

[Francois Bouchard]

Hi all,

I got a problem into my code that simply echos any incomming messages. 

First  have to cast (void *) to &buf because my compiler says its an error if I don't.

 

Secundo, the message transmitted by the server seems to be only half the original message length.

 

========================================================

    struct netbuf *inbuf;
    char *buf;
    u16_t buflen;
    err_t socket_error;

 

    inbuf = netconn_recv(conn);
    socket_error = netconn_err(conn);   
    
    if (socket_error == ERR_OK)    

    {

            netbuf_data(inbuf, (void*) &buf, &buflen);

            netconn_write(conn, (void*)buf, buflen, NETCONN_NOCOPY); 

    }

 

==========================================================     

 

See any flaws into the code?
