exception_dispatch_info.cpp

Shows how to use xtd::exception_services::exception_dispatch_info class.

#include <xtd/xtd>
 
auto main() -> int {
  auto capture_exception = exception_services::exception_dispatch_info {};
  
  thread::start_new([&] {
    try {
      throw invalid_operation_exception("Ouch there are an exception !");
    } catch (...) {
      capture_exception = exception_services::exception_dispatch_info::capture();
    }
  }).join();
  
  if (capture_exception) {
    try {
      console::write_line("Rethrow the captured exception :");
      capture_exception.rethrow();
    } catch (const exception& e) {
      console::write_line(e);
    }
  }
}
 
// This code can produce the following output :
//
// Rethrow the captured exception :
