|
|
|
<para>This exception policy throws a an exception derived from
|
|
<code>std::exception</code> any time some operation would result in an

<title>Example of use</title>
|
|
|
|
<para>This example is somewhat contrived as throw_exception is the default
|
|
for safe types. Hence it usually is not necessarily to request it
|
|
explicitly.</para>
