Hello everyone,
I want to access lib.pointer within a mexFile using Matlab's C++ API. The pointer is transported as matlab::data::ArrayType::HANDLE_OBJECT_REF, but I don't know how to access the values within this structure. I want to convert this to a void pointer later. The lib.pointer contains a handle to a device and I am using this to communicate with the device via a separate API.
Hopefully someone can help me further.
Thank you in advance.

lib.pointer has a Value property. Pass that to your MEX function.

Hmm ok but matlab is giving an error if I want to access the property:
The datatype and size of the value must be defined before the value can be retrieved.
The datatype of this libpointer is 'voidPtr'. Do you have a tip for me?
Thanks in advance!
