|
Sometimes we need to call a function and make sure that no user or system
|
|
originated exceptions are being thrown by it. Uniform exception reporting
|
|
is also may be convenient. That's the purpose of the Boost.Test's <span class="emphasis"><em>Execution
|
|
Monitor</em></span>.
|
|
</p>
|
|
<p>
|
|
The Execution Monitor is a lower-level component of the Boost Test Library.
|
|
It is the base for implementing all other Boost.Test components, but also
|
|
can be used standalone to get controlled execution of error-prone functions
|
|
with a uniform error notification. The Execution Monitor calls a user-supplied
|
|
function in a controlled environment, relieving users from messy error detection.
|
|
</p>
|
|
<p>
|
|
The Execution Monitor usage is demonstrated in the example <a href="../../../../../example/exec_mon_example.cpp" target="_top"><code class="literal">exec_mon_example.cpp</code></a>.
|
|
Additional examples are in <a class="link" href="section_pem.html" title="Program Execution Monitor">Program
|
|
Execution Monitor</a> or <span class="emphasis"><em>UTF</em></span>.

</h5>
|
|
<p>
|
|
The Execution Monitor design assumes that it can be used when no (or almost
|
|
no) memory available. Also the Execution Monitor is intended to be portable
|
|
to as many platforms as possible.
