Can C++ functions marked as Extern “C” throw?

Question

I\'ve got C++ functions that I want to declare using extern \"C\" even though they are only called in C++ code. Yes, I know this is strange but it\'s something

Answer 1

it will compile but it is undefined behavior to throw from function marked as having C linkage. C doesn't have exceptions, therefore in general you should just return an error code and/or provide a function that returns the information about the last error.

#include 
extern "C" void foo() {throw std::exception();}

compiles well
