Boost Exception

Configuration Macros

Boost Exception responds to the following configuration macros:

BOOST_NO_RTTI 
BOOST_NO_TYPEID

The first macro prevents Boost Exception from using dynamic_cast and dynamic typeid. If the second macro is also defined, Boost Exception does not use static typeid either. There are no observable degrading effects on the library functionality, except for the following:

By default, the get_error_info function template can be called with any exception type. If BOOST_NO_RTTI is defined, get_error_info can be used only with objects of type boost::exception.

BOOST_EXCEPTION_DISABLE

By default, enable_current_exception and enable_error_info are integrated directly in the throw_exception function. Defining BOOST_EXCEPTION_DISABLE disables this integration.

Note that on some non-conformant compilers, for example MSVC 7.0 and older, as well as BCC, BOOST_EXCEPTION_DISABLE is implicitly defined in boost/throw_exception.hpp.
