system_exception.cpp

Shows how to use system_exception exception.

#include <xtd/xtd>

using namespace xtd;

long create_handle() {
  return reinterpret_cast<long>(new guid());
}

void destroy_handle(long handle) {
  if (handle == 0) throw system_exception("The handle is null",  csf_);
  delete reinterpret_cast<object*>(handle);
}

auto main()->int {
  try {
    long handle = 0;
    // The following line is commented out so that the exception is generated.
    //handle = create_handle();
    
    destroy_handle(handle);
  } catch (const system_exception& e) {
    console::write_line("Exception occured :");
    console::write_line("-------------------");
    console::write_line(e);
  }
}

// This code can produces the following output :
//
// Exception occured :
// -------------------
// xtd::system_exception : The handle is null
