[det]tcp_connect(+Socket, +Address, -Read, -Write)

Connect a (client) socket to Address and return a bi-directional connection through the stream-handles Read and Write. This predicate may be hooked by defining socket:tcp_connect_hook/4 with the same signature. Hooking can be used to deal with proxy connections. E.g.,

:- multifile socket:tcp_connect_hook/4.

socket:tcp_connect_hook(Socket, Address, Read, Write) :-
    proxy(ProxyAdress),
    tcp_connect(Socket, ProxyAdress),
    tcp_open_socket(Socket, Read, Write),
    proxy_connect(Address, Read, Write).

deprecated: New code should use tcp_connect/3 called as tcp_connect(+Address, -StreamPair, +Options).
