<H3><a name="CPlusPlus11_noexcept"></a>7.2.25 Exception specifications and noexcept</H3>
<p>
C++11 added in the noexcept specification to exception specifications to indicate that a function simply may or may not throw an exception, without actually naming any exception.
SWIG understands these, although there isn't any useful way that this information can be taken advantage of by target languages,
so it is as good as ignored during the wrapping process.
Below are some examples of noexcept in function declarations:
</p>
<div class="code"><pre>
static void noex1() noexcept;
int noex2(int) noexcept(true);
int noex3(int, bool) noexcept(false);
</pre></div>
