Title
Body
I wanted to gain in-depth understanding of how programming languages implements exception handling and how exactly it works inside the hood. I have try to phrase this in many sub-questions as below. What is the mechanism used by programing languages to implement try { } catch { } blocks (under the hood)? How exactly stack unwinding works inside? What are the key differences between try { } / catch {} implementations between different languages like C++ and Java? Do they offer differ significantly or are they same? Is setjump/longjump method of stack rewinding in C is similar to try/throw/catch block? Why do people say that "stack unwinding" is costly? What exactly is SEH (Structured Exception Handling?)
