Example C++ library which internally throws an exception and catches it

sehlib.cxx

// g++ -O0 -shared -o sehlib.dll sehlib.cxx
// OR
// cl.exe /nologo /Od /MD /EHac /LD /Fe:sehlib.dll sehlib.cxx
#include <iostream>
#include <exception>

void throws_fn()
{
    std::cerr << "C++ throws exception" << std::endl;
    throw std::exception();
}

extern "C" __declspec(dllexport) void catches_fn()
{
    try
    {
        throws_fn();
    }
    catch(std::exception& e)
    {
        std::cerr << "C++ catches exception" << std::endl;
    }
}
