C++ Exception Programming

[pgav]

Hello, I'm trying to program a few exception classes for use in some software I'm working on. I'm more familliar with Java style of exception programming, and am having trouble finding some good API documentation on C++ exception classes. My plan was to inherit from exception, or runtime_error, however I can't find figure out what methods I'm inheriting without a good API. Does anone know of a good API page on the exeption classes? Thanks. Patrick

Thanks for the link, that puts me on the right trak; however, considering the following example: // standard exceptions #include #include using namespace std; class myexception: public exception { virtual const char* what() const { return "My exception happened"; } } myex; int main () { try { throw myex; } catch (exception& e) { cout << e.what() << endl; } return 0; } This example does part of what I'm looking for, however I'd like to have more options when using the exception class. I'd like to give the programmer the option of passing in their own error message to the exception class, or to just use the default. Anyone know where I can look fir this? Thanks.

With C++ exceptions, you can throw any object, even an int if you feel like it. There is no base exception class. (STL has an exception class, but it's very limited.) I STRONGLY suggest writing your own exception class and write it to fit your requirements. Anyone who thinks he has a better idea of what's good for people than people do is a swine. - P.J. O'Rourke

What Joe Woodbury said is correct. The C++ base exception class only defines what() so unless you want to use that you can just create your own base exception class to your own design requirements.
