<tt>Hi Steven.<br>
<br>
Simply try to include </tt><b>Winsock2.h</b>.<br>
<tt>Here is MSDN:<br>
</tt>
<h1>SOCKADDR_STORAGE</h1>
<p>The <b>SOCKADDR_STORAGE</b> structure stores socket address
information. Since the <b>SOCKADDR_STORAGE</b> structure is
sufficiently large to store IPv4 or IPv6 address information, or
others, its use promotes protocol-family and protocol-version
independence, and simplifies cross-platform development. Use the <b>SOCKADDR_STORAGE</b>
structure in place of the <a href="sockaddr_2.htm"><b>sockaddr</b></a>
structure.</p>
<pre class="syntax" xml:space="preserve">typedef struct sockaddr_storage {
short <a class="synParam" onclick="showTip(this)" href="">ss_family</a>;
char <a class="synParam" onclick="showTip(this)" href="">__ss_pad1</a>[_SS_PAD1SIZE];
__int64 <a class="synParam" onclick="showTip(this)" href="">__ss_align</a>;
char <a class="synParam" onclick="showTip(this)" href="">__ss_pad2</a>[_SS_PAD2SIZE];
} SOCKADDR_STORAGE,
*PSOCKADDR_STORAGE;</pre>
<h4>Members</h4>
<dl>
<dt><b>ss_family</b> </dt>
<dd>Address family of the socket, such as AF_INET. </dd>
<dt><b>__ss_pad1</b> </dt>
<dd>Reserved. Defined as a 48-bit pad that ensures <b>SOCKADDR_STORAGE</b>
achieves 64-bit alignment. </dd>
<dt><b>__ss_align</b> </dt>
<dd>Reserved. Used by the compiler to align the structure. </dd>
<dt><b>__ss_pad2</b> </dt>
<dd>Reserved. Used by the compiler to align the structure. </dd>
</dl>
<h4>Remarks</h4>
<p>Application developers use only the <b>ss_family</b> member of the <b>SOCKADDR_STORAGE</b>.
The remaining three members ensure the <b>SOCKADDR_STORAGE</b> is
padded appropriately to achieve 64-bit alignment. Such alignment
enables protocol-specific socket address data structures to access
fields within a <b>SOCKADDR_STORAGE</b> structure without alignment
problems. With its padding, the <b>SOCKADDR_STORAGE</b> structure is
128 bytes in length.</p>
<p>The member field of the <b>SOCKADDR_STORAGE</b> structure is
isomorphic with the <a href="sockaddr_2.htm"><b>sockaddr</b></a>
structure to enable simplified transition from sockaddr to <b>SOCKADDR_STORAGE</b>.</p>
<p>For more information about platform-independent <b>SOCKADDR_STORAGE</b>
implementation recommendations, refer to RFC 2553, available at <a
href="http://www.ietf.org" target="_blank">www.ietf.org</a>.</p>
<h4>Requirements</h4>
<p><b>Client: </b>Requires WindowsXP.<br>
<b>Server: </b>Requires Windows Server2003.<br>
<b>Header: </b>Declared in <u><b><font color="#ff0000">Winsock2.h</font></b></u>.<br>
