socket_listen - Man Page

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: ");
