std::terminate_handler set_terminate( std::terminate_handler f ) noexcept;
(since C++11)

Makes f the new global terminate handler function and returns the previously installed std::terminate_handler.

This function is thread-safe. Every call to std::set_terminate synchronizes-with (see std::memory_order) the subsequent std::set_terminate and std::get_terminate

(since C++11)


f - pointer to function of type std::terminate_handler, or null pointer

Return value

The previously-installed terminate handler, or a null pointer value if none was installed.


#include <iostream>
#include <cstdlib>
#include <exception>
int main()
    std::set_terminate([](){ std::cout << "Unhandled exception\n"; std::abort();});
    throw 1;

Possible output:

Unhandled exception
bash: line 7:  7743 Aborted                 (core dumped) ./a.out
