NAME¶
socket_listen - attempt to make a TCP connectionSYNTAX¶
#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: ");
