socket_listen(3diet)
NAME
socket_listen - attempt to make a TCP connection
SYNTAX
#include <socket.h>
int socket_listen(int s,int n);
DESCRIPTION
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.
EXAMPLE
#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: ");
