Sample Function would have to be a static function and you would need use the & modifier to get the address of the function. If that does not clarify it for you I think you'd need to paste the code that is not working for you.
@mhdawson Hi, I've tried everything I can think of, including this answer that shows how to do it, but unfortunately, that doesn't work either, I'm guessing because it's either outdated, or I'm just an idiot, but the error message is the same:
error C2664: 'v8::Local<v8::FunctionTemplate> v8::FunctionTemplate::New(v8::Isolate *,v8::FunctionCallback,v8::Local<v8::Value>,v8::Local<v8::Signature>,int,v8::ConstructorBehavior,v8::SideEffectType)': cannot convert argument 2 from 'v8::Local<v8::Value> (__cdecl *)(const v8::FunctionCallbackInfo<v8::Value> &)' to 'v8::FunctionCallback'@mhdawson Hi, yes, I do have an example of the code, here. The error is this:
window.cpp(25): error C2664: 'v8::Local<v8::FunctionTemplate> v8::FunctionTemplate::New(v8::Isolate *,v8::FunctionCallback,v8::Local<v8::Value>,v8::Local<v8::Signature>,int,v8::ConstructorBehavior,v8::SideEffectType)': cannot convert argument 2 from 'v8::Local<v8::Value> (__cdecl *)(const v8::FunctionCallbackInfo<v8::Value> &)' to 'v8::FunctionCallback'It would also be worth mentioning the declaration of the
BackgroundCBfunction in the header file:static v8::Handle<v8::Value> BackgroundCB(const v8::FunctionCallbackInfo<v8::Value> &args);Ok so I missed that you are not using N-API? The examples are more up to date and supported on that side of things. Can you not use N-API for some reason?
I'm not using N-API because in my opinion, it's best to learn a language/framework without additional layers of abstraction first, plus libraries in general just don't seem to work. As in, they simply won't compile.
But I'll look into it.
Hi, anyone reading this,
The file
node-addon-examples/5_function_factory/node_0.12/addon.cccontains a function factory, that's all well and good, but when I do something similiar, instead of using a global function, I'm using an instance function, (sorry, bad C++ vocab, I'm only new...) a function that's a private member of a class, and I want to use that as the function body, where the example usesas the body. The issue is I get an error when doing this, the error is as follows:
error C3867: 'Class::SampleFunction': non-standard syntax; use '&' to create a pointer to memberand I have no idea what to do about it.
