Exporting a function pointer from dll

Question

I have a function pointer in a dll file (in implementation, not header). How can I call the function pointed to by this pointer in the exe source code?

If it is declared with global scope then you can just export the variable directly. That's pretty open to abuse though. — David Heffernan, Oct 14 '11 at 08:00
It's just not very well encapsulated. But it is perfectly normal and common to export variables from DLLs. And a function pointer is just a variable. — David Heffernan, Oct 15 '11 at 19:29

you can export a function returning the pointer. Header:

typedef void ( *MyPtr ) ();

__declspec( dllexport ) MyPtr GetMyPtr();

Source:

MyPtr GetMyPtr()
{
  //retunr the function pointer here
}

Or better and more flexible, fill in a struct of function pointers passed by pointer. – Zan Lynx Oct 14 '11 at 07:23
