Re: Rethrow from other place than catch-block

Hi,

Is it legal to rethrow an exception from a function called from the
catch block?

Is the following program legal C++?

#include <iostream>
using namespace std;
void ExceptionHandler(const char* context)
{
     cout << "In ExceptionHandler(" << context << "):";
     try // Setup a new try-block and rethrow the exception
     {
         throw;
     }
     catch (const int& e)
     {
         cout << "int = " << e << "\n";
     }
     catch (const char* e)
     {
         cout << "text = " << e << "\n";
     }
     catch (...)
     {
         cout << "UNKNOWN\n";
     }
}
int _tmain(int argc, _TCHAR* argv[])
{
     for (int i = 0; i < 5; ++i)
     {
         try
         {
             switch (i)
             {
             case 0: throw 42;
             case 1: throw "Some text";
             case 2: throw 12.4;
             case 3: cout << "Still alive\n"; break;
             case 4:
                 {
                     try
                     {
                         throw "Another text";
                     }
                     catch (...)
                     {
                         ExceptionHandler("Other context");
                     }
                 }
                 break;
             }
         }
         catch (...) // Catch all exceptions here
         {
             ExceptionHandler("Inside for loop");
         }
     }
     return 0;
}
