callback for mbl_mw_datasignal_subscribe in c# wrapper

jrood

I'm looking at the mbl_mw_datasignal_subscribe in Functions.cs in the c# wrapper, and I'm expecting the second parameter to be a handler/callback function that does something with a pointer, but instead it's just the pointer. Am I misunderstanding how this should be used, or is this a bug in the wrapper?

The second parameter is a delegate that accepts an IntPtr, as defined in the Core.cs class.

Ok, I see. So then, do you know how I could determine whether the IntPtr should be marshaled to a uint, float, or CartesianFloat? (If the delegate was accepting the MbientLab.MetaWear.Core.Data object, I would just check the typeId property)

Eric

Marshal the IntPtr to a Core.Data object

Oh nice, thanks
