Trying To Learn 'extern'

[zb0S216C]

I'm trying to learn how to use the extern keyword. I'm not understanding it very good if I'm honest. So far, this is what I've got:

extern "C"
{
    struct Struct
    {
        int Value;
    };

    int Struct_Init( struct Struct *This_object, int Init_value );
}

int main( )
{
    //...
}

How would I call Struct_Init( ) as if it were a C++ method? Any resources or an example will be appreciated.

All extern "C" says in this case is that the compiler should not mangle the names inside the extern C block. This means that if you had a pure C file which you compiled with the C compiler, you would be able to call the function.

From a programming standpoint, you use them the same way either way.

That makes sense. Thanks jsmith.
