std::signal is an STL function to set a function to respond to system signals.

In the example below, an assert is set to fail, causing std::abort, which emits the abort signal ('SIGABRT'). With std::signal onAbort is set to handle this.


#include <cassert>

#include <csignal>

#include <iostream>



void onAbort(int)

{

  std::cout << "Abort" << std::endl;

}



int main()

{

  std::signal(SIGABRT,onAbort);

  assert(1==2);

}
