- Establish a TCP communication as a client. The +,-,+ mode is the
preferred way for a client to establish a connection. This predicate
can be hooked to support network proxies. To use a proxy, the hook
proxy_for_url/3 must be defined. Permitted options are:
- bypass_proxy(+Boolean)
- Defaults to
false. Iftrue, do not attempt to use any proxies to obtain the connection - nodelay(+Boolean)
- Defaults to
false. Iftrue, set nodelay on the resulting socket usingtcp_setopt(Socket, nodelay) - domain(+Domain)
- One of `inet' or
inet6. When omitted we use host_address/2 withtype(stream)and try the returned addresses in order.
The +,+,- mode is deprecated and does not support proxies. It behaves like tcp_connect/4, but creates a stream pair (see stream_pair/3).
- Arguments:
-
Address - is either a Host:Port term or a file name (atom or string). The latter connects to an AF_UNIX socket and requires unix_domain_socket/1. - Errors
- -
proxy_error(tried(ResultList))is raised by mode (+,-,+) if proxies are defines by proxy_for_url/3 but no proxy can establsh the connection. ResultList contains one or more terms of the formfalse(Proxy)for a hook that simply failed orerror(Proxy, ErrorTerm)for a hook that raised an exception. - See also
- - library(http/http_proxy) defines a hook that allows to connect
through HTTP proxies that support the
CONNECTmethod.
