std::set_terminate (3) Linux Manual Page

std::set_terminate – std::set_terminate

Synopsis

Defined in header <exception>
std::terminate_handler set_terminate( std::terminate_handler f ) throw(); (until C++11)
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)

Parameters

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.

Example

// Run this code

#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
