<div class="RenoIncludeDIV"><div class="RenoAutoDIV"><h2>Diagnostic Information</h2>
|
|
</div>
|
|
<p>Boost Exception provides a namespace-scope function <span class="RenoLink"><a href="diagnostic_information.html">diagnostic_information</a></span> which takes a boost::<span class="RenoLink"><a href="exception.html">exception</a></span>. The returned string contains:</p>
|
|
<div><ul><li>the string representation of all data objects added to the boost::<span class="RenoLink"><a href="exception.html">exception</a></span> through <span class="RenoLink"><a href="exception_operator_shl.html">operator<<</a></span>;</li>
|
|
<li>the output from std::exception::what;</li>
|
|
<li>additional platform-specific diagnostic information.</li>
|
|
</ul></div>
|
|
<p>The returned string is not presentable as a friendly user message, but because it is generated automatically, it is useful for debugging or logging purposes. Here is an example:</p>
|
|
<pre>#include <<span class="RenoLink"><a href="exception_hpp.html">boost/exception.hpp</a></span>>
|
|
#include <iostream>
|
|
|
|
void f(); //throws unknown types that derive from boost::<span class="RenoLink"><a href="exception.html">exception</a></span>.
|
|
|
|
void
|
|
g()
|
|
{
|
|
try
|
|
{
|
|
f();
|
|
}
|
|
catch(
|
|
boost::<span class="RenoLink"><a href="exception.html">exception</a></span> & e )
|
|
{
|
|
std::cerr << <span class="RenoLink"><a href="diagnostic_information.html">diagnostic_information</a></span>(e);
|
|
}
|
|
}</pre>
|
|
<div class="RenoIncludeDIV"><h4>Example:</h4>
