Sometimes you have a function name with the same name as a C macro,
for example "min" and "max" member functions,
in which case one can prevent the function being expanded as a
macro using:
</p>
<pre xmlns:rev="http://www.cs.rpi.edu/~gregod/boost/tools/doc/revision" class="table-programlisting"><span class="identifier">someclass</span><span class="special">.</span><span class="identifier">min</span> <span class="identifier">BOOST_PREVENT_MACRO_SUBSTITUTION</span><span class="special">(</span><span class="identifier">arg1</span><span class="special">,</span> <span class="identifier">arg2</span><span class="special">);</span>
</pre>
<p>
The following also works in most, but not all, contexts:

contexts. This macro expands to nothing on those compilers, and typename
