basic_stream::connect (6 of 10 overloads)

Establishes a connection by trying each endpoint in a sequence.

Synopsis
template<
    class Iterator>
Iterator
connect(
    Iterator begin,
    Iterator end,
    error_code& ec);
Description

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.

Parameters

Name

Description

begin

An iterator pointing to the start of a sequence of endpoints.

end

An iterator pointing to the end of a sequence of endpoints.

ec

Set to indicate what error occurred, if any. If the sequence is empty, set to boost::asio::error::not_found. Otherwise, contains the error from the last connection attempt.

Return Value

On success, an iterator denoting the successfully connected endpoint. Otherwise, the end iterator.
