Catching Accessing Violations

Hi !

I'm familiar with the throw and catch statements as well as the THROW and CATCH, CATCH_ALL macros of Visual C++. I'm wondering how can I use these statements to catch access violation exceptions. In ADA, for example, these access violations would be captured using the exception identifier and the type of the exception would be a CONSTRAINT_ERROR. Is there a similar thing in C++ where I can catch constraint/access violations without checking the pointer against NULL. There are times when the pointer is not NULL but is pointing to an invalid object.

Thank you.
