Wren expects this function to return a pointer to a function that takes a WrenVM*. This is bad news because that type is wrapped inside wren::VM and client code doesn't know about it. It would be better for client code to return a pointer to a function that takes a VM* instead. In order to do the VM* to WrenVM* translation I make a "handmade" closure, that is I generate a function at runtime that contains the VM* hardcoded into it. The same function also contains the hardcoded address of the callback function client code wanted to use. By doing this I can pass a different function pointer to Wren for each foreign method, and that function knows how to forward the call to the real client callback. Currently only implemented for amd64 gnu/linux. |
