How to call user-defined C function having return and arguments with GetSet storage class

I am developing a Stateflow model where I need to call user defined C functions. The function prototype could be as follows
uint8 getset_Func(uint8 arg1, uint8 arg2, uint8 *arg3);
I have defined signal FuncCall with sorage class as GetSet and function header file is added in the code generation option.
I have added the option GetFunction as getset_$N and SetFunction option is empty.
But I am not able to use the signal in the stateflow. I have tried to use as var = FuncCall(temp1, temp2, &temp3);
This is giving error Unresolved function 'FuncCall'
How can I pass the arguments and return the result at the same time using GetSet storage class.

You should use coder.ceval() to call external C code from Stateflow. https://www.mathworks.com/help/simulink/slref/coder.ceval.html
You would write code similar to the folloiwng but substituting the name of your .c and .h files.
arg1 = uint8(4);
arg2 = uint8(5)
arg3 = uint8(6);
var = uint8(8);
coder.updateBuildInfo('addSourceFiles','foo.c');
coder.cinclude('foo.h');
var = coder.ceval("getset_Func", arg1, arg2, arg3 );
