std::terminate_handler: std::terminate_handler

NAME

std::terminate_handler - std::terminate_handler

Synopsis

Defined in header <exception>
typedef void (*terminate_handler)();

std::terminate_handler is the function pointer type (pointer to function that takes no arguments and returns void), which is installed and queried by the functions std::set_terminate and std::get_terminate and called by std::terminate.
The C++ implementation provides a default std::terminate_handler function, which calls std::abort(). If the null pointer value is installed (by means of std::set_terminate), the implementation may restore the default handler instead.
