## `BOOST_STATIC_WARNING`

The header `<boost/static_warning.hpp>` supplies a single macro `BOOST_STATIC_WARNING(x)`, which generates a compile time warning message if the integral-constant-expression x is not true.

Note that if the condition is true, then the macro will generate neither code nor data - and the macro can also be used at either namespace, class or function scope. When used in a template, the expression x will be evaluated at the time the template is instantiated; this is particularly useful for validating template parameters.

It is intended that the functioning of `BOOST_STATIC_WARNING(x)` be identical to that of `BOOST_STATIC_ASSERT(x)` except that rather than resulting in a compilation error, it will result in a compiler warning. In all other respects it should be the same. So for more information on using `BOOST_STATIC_WARNING(x)` consult the documentation for `BOOST_STATIC_ASSERT(x)` here.
