How to build a C++ Dll wrapper that catches all exceptions?
- by bart de vries
Like the title says, we’re looking for a way to catch all exceptions from a piece of C++ code, and wrap this in a dll. This way we can shield of the application that uses this dll, from any errors occurring in this dll.
However, this does not seem possible with C++ under Windows.
Example:
void function()
{
try
{
std::list<int>::iterator fd_it;
fd_it++;
} catch(...) {}
}
The exception that occurs is not caught by the standard C++ try/catch block, nor by any SEH translator function set by _set_se_translator(). Instead, the DLL crashes, and the program that uses the DLL is aborted. We compiled with Visual C++ 2005, with the option /SHa. Does anyone know if it’s possible in C++/Win32 to catch these kind of problems and make a rocksolid DLL wrapper?
