How do I access chart data inside MATLAB Functions in state flow?

I want to access all data (input, local, output) defined in a chart inside MATLAB Functions, defined in that chart. We can pass the data as input to the function but there can be dozens of input arguments (in my case). In C, we can declare variable as global and access them anywhere in any function without passing them as input arguments. How can I achieve that in stateflow? Also, is there a way to define structures so that there may be a single input and output to a given function? Ultimately, my goal is to generate a C code.

By default, a MATLAB function can access chart and state data above it in the Stateflow hierarchy. For more information, see https://www.mathworks.com/help/stateflow/ug/matlab-functions-in-a-chart.html.
