Hello
Colleagues, I have some question about accept(2) functions.
I have wrote the following programm:
-------------------------------
/* set up the listening tcp socket*/
if ( (l_fd = socket(AF_INET, SOCK_STREAM, 0)) < 0)
{ log_error("socket (tcp) error"); exit(0); }
memset(&l_servaddr,0,sizeof(l_servaddr));
l_servaddr.sin_family = AF_INET;
l_servaddr.sin_addr.s_addr = htonl(INADDR_ANY);
l_servaddr.sin_port = htons(c_tcpport);
if ( bind(l_fd,(struct sockaddr *) &l_servaddr, sizeof(l_servaddr)) < 0)
{ log_error ("bind TCP error"); exit(0); }
if ( listen(l_fd, 32) < 0)
{ log_error("listen error"); exit(0); }
if ( (l_connfd = accept(l_fd,(struct sockaddr *) l_cliaddr, &l_addrlen))
< 0)
{ log_error("accept error"); exit(0); }
----------------------------------------
I'm trying to find out the client ip that connects to this server.
But l_cliaddr structure is NULL after succesfull accept call.
As I understand from manuals in this structure must be client ip.
Where I'm wrong and how I can get this ip?
Thank you for advance.

With best regards.
