[#BSLS_EXCEPTION_VIRTUAL_NOTHROW]
= BSLS_EXCEPTION_VIRTUAL_NOTHROW
:mrdocs:

The exception specification that overrides of the virtual destructor and the `exception::what()` virtual method should use. It is a separate macro from `BSLS_NOTHROW_SPEC` because the GNU library unconditionally declares the function `throw()`, regardless if exceptions are enabled or not ‐ and overrides must do the same.

== Synopsis

Declared in `<bsls_exceptionutil.h>`
