socket_listen - attempt to make a TCP connection
#include <socket.h>
int socket_listen(int s,int n);
socket_listen prepares TCP socket s to accept TCP connections. It allows a backlog of approximately n TCP SYNs. (On systems supporting SYN cookies, the backlog is irrelevant.) Normally socket_listen returns 0.
If anything goes wrong, socket_listen returns -1, setting errno appropriately.
#include <socket.h>
int s;
char ip[16];
uint16 p;
if ((s=socket_tcp6())==-1)
strerr_die2sys(111,FATAL,"unable to create TCP socket: ");
if (socket_bind6_reuse(s,(char *)V6any,8002,0) == -1)
strerr_die2sys(111,FATAL,"unable to bind: ");
if (socket_listen(s,1) == -1)
strerr_die2sys(111,FATAL,"unable to listen: ");
