So, I have a big piece of legacy software, coded in C. It’s for an embedded system, so if something goes wrong, like divide by zero, null pointer dereference, etc, there’s not much to do except reboot.

I was wondering if I could implement just main() as c++ and wrap it’s contents in try/catch. That way, depending on the type of exception thrown, I could log some debug info just before reboot.

Hmm, since there are multiple processes I might have to wrap each one, not just main(), but I hope that you see what I mean…

Is it worthwhile to leave the existing C code (several 100 Klocs) untouched, except for wrapping it with try/catch?

    Division by zero or null pointer dereferencing don’t produce exceptions (using the C++ terminology). C doesn’t even have a concept of exceptions. If you are on an UNIX-like system, you might want to install signal handlers (SIGFPE, SIGSEGV, etc.).
