<para>
Initiates a connection using the socket resource
<parameter>socket</parameter>, which must be a valid socket
resource created with <function>socket_create</function>.
</para>
<para>
The <parameter>address</parameter> parameter is either an IP
address in dotted-quad notation
(e.g. <literal>127.0.0.1</literal>), if the socket is of the
<constant>AF_INET</constant> family; or the pathname of a
Unix domain socket, if the socket family is
<constant>AF_UNIX</constant>.
</para>
<para>
The <parameter>port</parameter> parameter is only used when
connecting to an <constant>AF_INET</constant> socket, and
designates the port on the remote host to which a connection
should be made.
</para>
<para>
&return.success; The error code can be retrieved with
<function>socket_last_error</function>. This code may be passed to
<function>socket_strerror</function> to get a textual explanation of the
error.
</para>
