When used in a template, the expression x 36will be evaluated at the time the template is instantiated; this is 37particularly useful for validating template parameters. 38<p> 39It is intended that the functioning of <code style="white-space: normal">BOOST_STATIC_WARNING(x)</code> 40be identical to that of <code style="white-space: normal">BOOST_STATIC_ASSERT(x)</code> 41except that rather than resulting in a compilation error, it will result in 42a compiler warning. In all other respects it should be the same. So 43for more information on using <code style="white-space: normal">BOOST_STATIC_WARNING(x)</code> 44consult the documentation for <code style="white-space: normal">BOOST_STATIC_ASSERT(x)</code> 45<a href="../../../doc/html/boost_staticassert.html">here</a>. 46 47<hr> 48<p><i>© Copyright <a href="http://www.rrsd.com">Robert Ramey</a> 2002-2004. 49Distributed under the Boost Software License, Version 1.0.
