Can I make function `extern "c"`?

I have some cpp files, and I want to combine them with LuaJit using FFI.

But the problem is that, I have to add extern "c" symbols for almost every function to make it possible for FFI to access them.

Is there a simpler way to make this done?

Solution

  • Several functions can be placed inside a single extern "C" block. This allows you to type extern "C" only once for each header file. 

    extern "C" {
    void function1();
    void function2();
}
