[lwip-users] access to tcp_pcb data from socket+

[Mattia Settin]

Dear all

I developing an application wih lwip 2.0.3 using socket bsd.

The tcp server performs the following operation:

s = socket()

bind

accept //wait a new connection

read  //packet received

I need to perform some check on the pcb data of my socket.

I note the get_socket is defined as static and the get_sockopt do not return all data I need.

I solve adding following function in socket.c:

struct tcp_pcb * lwip_getsockpcb(int s)
{
  struct lwip_sock *sock = get_socket(s);
  if (!sock) {
    return NULL;
  }
  return sock->conn->pcb.tcp;
}

My question is:

how can acces to the tcp_pcb of my socket with out modify the library ?

Which is the smart way ?

Thank all

regard
