Detailed Description

This namespace serves two purposes.

This namespace is used for two things:

• sequestering internal (implementation-only) names away from the global namespace; these are details of the implementation and should not be touched by users
• GNU extensions for public use

This is still fluid and changing rapidly. Currently the rule is: if an entitity is found in the user-level documentation, it falls into the second category.

Function Documentation

void __gnu_cxx::__verbose_terminate_handler (   )

A replacement for the standard terminate_handler which prints more information about the terminating exception (if any) on stderr. Call std::set_terminate (__gnu_cxx::__verbose_terminate_handler) to use. For more info, see http://gcc.gnu.org/onlinedocs/libstdc++/19_diagnostics/howto.html#4 In 3.4 and later, this is on by default.
