Method connect

int connect(string host, int|string port, void|string client, void|int|string client_port)


This function connects a socket previously created with open_socket() to a remote socket through TCP/IP. The host argument is the hostname or IP number of the remote machine. A local IP and port can be explicitly bound by specifying client and client_port.


This function returns 1 for success, 0 otherwise.


In nonblocking mode 0 (zero) may be returned and errno() set to EWOULDBLOCK or WSAEWOULDBLOCK. This should not be regarded as a connection failure. In nonblocking mode you need to wait for a write or close callback before you know if the connection failed or not.
