Throw Exceptions - unexpected and terminate functions

[xgiovio]

set_unexpected called because the function hasn't permission to throw exceptions. After, terminate function is launched.

#include <iostream>
#include <string>
#include <stdexcept>


using namespace std;

////////////////////////// samaple class

class DivideForZeroException : public runtime_error {
public:
    DivideForZeroException()
    : runtime_error("Impossibile dividere per 0\n")
    {}
};


///////////// termiante and unexpected functions


void terminate_function(){
    cout << "terminate_function" << endl;
}

void unexpected_function(){
    cout << "unexpected_function" << endl;
}



////////////// the function called to throw excpetion

void function() throw(){

    try{
        throw DivideForZeroException();
    }
    catch (DivideForZeroException  & error){
        throw ;
    }

}



int main (void){
    
    set_terminate(terminate_function);
    set_unexpected(unexpected_function);
    
    ::function();

    return 0;
}

Same version but the function can throw any exception. So the unexpected function isn't launched.

#include <iostream>
#include <string>
#include <stdexcept>


using namespace std;

////////////////////////// samaple class

class DivideForZeroException : public runtime_error {
public:
    DivideForZeroException()
    : runtime_error("Impossibile dividere per 0\n")
    {}
};


///////////// termiante and unexpected functions


void terminate_function(){
    cout << "terminate_function" << endl;
}

void unexpected_function(){
    cout << "unexpected_function" << endl;
}



////////////// the function called to throw excpetion

void function() {

    try{
        throw DivideForZeroException();
    }
    catch (DivideForZeroException  & error){
        throw ;
    }

}



int main (void){
    
    set_terminate(terminate_function);
    set_unexpected(unexpected_function);
    
    ::function();

    return 0;
}
