<p>The server parameter can be any of several different forms:</p>
<ul>
<li><b>0</b>: Let the database driver decide how to connect; usually some sort of localhost IPC method.</li>
<li><b>"."</b>: On Windows, this means named pipes, if the server supports it</li>
<li><b>"/some/domain/socket/path"</b>: If the passed string doesn't match one of the previous alternatives and we're on a system that supports Unix domain sockets, MySQL++ will test it to see if it names one, and use it if we have permission.</li>
<li><b>"host.name.or.ip:port"</b>: If the previous test fails, or if the system doesn't support Unix domain sockets at all, it assumes the string is some kind of network address, optionally followed by a colon and port. The name can be in dotted quad form, a host name, or a domain name. The port can either be a TCP/IP port number or a symbolic service name. If a port or service name is given here and a nonzero value is passed for the <code>port</code> parameter, the latter takes precedence. </li>

<p>The MySQL++ user manual's <a href="../userman/threads.html">chapter on threads</a> details two major strategies for dealing with connections in the face of threads. The Connection-per-thread option frees you from ever having to call this method. The other documented strategy is to use <a class="el" href="classmysqlpp_1_1ConnectionPool.html" title="Manages a pool of connections for programs that need more than one Connection object at a time,...">ConnectionPool</a>, which opens the possibility for one thread to create a connection that another uses, so you do need to call this method in that case, or with any other similar strategy.</p>
