C++ Exceptions

[edmcman]

It seems like any code containing C++ exceptions will cause a compilation error.

class MyException
{
 public:
  MyException() { }
  ~MyException() { }
};

void my_throwing_function(bool throwit)
{
  if (throwit)
    throw MyException();
}

void another_function();
void log(unsigned count);

void my_catching_function()
{
  log(0);
    try
      {
        log(1);
        another_function();
        log(2);
      }
    catch (const MyException& e)
      {
        log(3);
      }
    log(4);
}

softboundcets does not handle C++ code yet.

[edmcman]

Good to know! Luckily the C++ code that was failing was a C++ interface that was not actually related to the code I was testing.

Hi,

softboundcets does not handle C++ code yet

is this still valid?

Thanks
