c++ - cpp: catch exception with ellipsis and see the information -

i know can catch "all exceptions" , print exception

try {     //some code... }catch(const std::exception& e) {    cout << e.what(); }

but exceptions derived std::exception. wondering if there way information ellipsis catch

try {     //some code... }catch(...) {    // ?? }

if mechanism same ellipsis functions should able casting argument of va_list , trying call what() method.

i haven't tried yet if knows way i'd excited know how.

sorry, can't that. can access exception object in catch block specific exception type.

TY
