<h4>Description:</h4>
<p>This class template is used to associate a Tag type with a value type T. Objects of type <span class="RenoLink">error_info</span>&lt;Tag,T&gt; can be passed to <span class="RenoLink"><a href="exception_operator_shl.html">operator&lt;&lt;</a></span> to be stored in objects of type boost::<span class="RenoLink"><a href="exception.html">exception</a></span>.</p>
<h4>Usage:</h4>
<p>The header &lt;<span class="RenoLink"><a href="exception_error_info_value_hpp.html">boost/exception/error_info.hpp</a></span>&gt; provides a declaration of the <span class="RenoLink">error_info</span> template, which is sufficient for the purpose of typedefing an instance for specific Tag and T, for example:</p>
<pre>#include &lt;<span class="RenoLink"><a href="exception_error_info_value_hpp.html">boost/exception/error_info.hpp</a></span>&gt;

struct tag_errno;
typedef boost::<span class="RenoLink">error_info</span>&lt;tag_errno,int&gt; errno_info;</pre>
