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.

terminate_handler std::set_terminate (  terminate_handler   )  throw ()

Takes a new handler function as an argument, returns the old function.

unexpected_handler std::set_unexpected (  unexpected_handler   )  throw ()

Takes a new handler function as an argument, returns the old function.

void std::terminate (   )

The runtime will call this function if exception handling must be abandoned for any reason. It can also be called by the user.

bool std::uncaught_exception (   )  throw ()

[18.6.4]/1: "Returns true after completing evaluation of a throw-expression until either completing initialization of the exception-declaration in the matching handler or entering unexpected() due to the throw; or after entering terminate() for any reason other than an explicit call to terminate(). [Note: This includes stack unwinding [15.2]. end note]" 2: "When uncaught_exception() is true, throwing an exception can result in a call of terminate() (15.5.1)."

void std::unexpected (   )

The runtime will call this function if an exception is thrown which violates the function's exception specification.
