Device Driver Block BUS output from C++ map

Hi.
We developed a device driver following the guidelines at https://nl.mathworks.com/help/supportpkg/raspberrypi/device-driver-blocks.html
We developed the C function to be called which, after querying the device, returns a map<string, double> (basically a bus with signal names and values).
The function has been tested (on a standalone program built on the RPI) and it works correctly.
What it's not clear is how to invoke correctly the function that we wrote so that matlab can correctly interpret the returned data.
In other words: if my function returns a map can it be called through coder.ceval? Do I need to use easier types?
Any help appreciated.
Thanks in advance.

When using “coder.ceval” in MATLAB, the function being called should have a C-compatible signature and return type. If your function returns a MATLAB “containers.Map” object, which is not a C-compatible type, you cannot directly call it using “coder.ceval”.
You can refer to the below documentation link of “container.Map” for further reference.
