###### basic_stream::connect (4 of 10 overloads)

Establishes a connection by trying each endpoint in a sequence.

<h7> Synopsis </h7>

    template<
        class EndpointSequence>
    Protocol::endpoint
    connect(
        EndpointSequence const& endpoints,
        error_code& ec);

<h7> Description </h7>

This function attempts to connect the stream to one of a sequence of endpoints by trying each endpoint until a connection is successfully established. The underlying socket is automatically opened if needed. An automatically opened socket is not returned to the closed state upon failure. The algorithm, known as a composed operation, is implemented in terms of calls to the underlying socket's `connect` function.

<h7> Parameters </h7>

Name | Description
--- | ---
`endpoints` | A sequence of endpoints.
`ec` | Set to indicate what error occurred, if any. If the sequence is empty, set to `net::error::not_found`. Otherwise, contains the error from the last connection attempt.

<h7> Return Value </h7>

On success, the successfully connected endpoint. Otherwise, a default-constructed endpoint.
