C/C++ Addon: Is argument a Buffer instance?

[Bodo Kaiser]

Hello,

I want to move my bit operations parser from Js to C(++).

My current problem is that I do not know how to check if the argument is a buffer instance.

GetIndexedPropertiesExternalArrayDataType() returns an enum with the types but I am not sure what to do with it...

Local<Object> obj = args[0]->ToObject();

if (obj->GetIndexedPropertiesExternalArrayDataType() != kExternalFloatArray) return;

Use Buffer::HasInstance: https://github.com/joyent/node/blob/v0.10/src/node_buffer.h#L73
