Beispiel

#include <iostream>#include <string>#include <exception>#include <stdexcept>   void handle_eptr(std::exception_ptr eptr)// passing by value is ok{try{if(eptr !=std::exception_ptr()){ std::rethrow_exception(eptr);}}catch(conststd::exception& e){std::cout<<"Caught exception \""<< e.what()<<"\"\n";}}   int main(){std::exception_ptr eptr;try{std::string().at(1);// this generates an std::out_of_range}catch(...){ eptr =std::current_exception();// capture} handle_eptr(eptr);}// destructor for std::out_of_range called here, when the eptr is destructed

Output:

Caught exception "basic_string::at"
