How to call a function that uses a function pointer argument from Simulink?

I want to load the following C code function as the C -Caller in the simulink.
There is no build error, but I can't find the function in the Function name.
I think, it can't recognize Void (*func) (CONST IF_AppDiagStatus_t), one of the argument of the function. (Use of function pointer)
Is there a way to solve this?
********************************************************************************************************************************************
void IF_AppDiagSetFuncForGetDiagStatus(void(*func)(CONST IF_AppDiagStatus_t), CONST App_ID_e appID)
{
if (appID < APP_ID_END)
{
appDiagGetFunc[appID].getDiagStatusFunc = func;
}
}

Simulink only supports certain data types as inputs to blocks: integers, double, single, busses, enumerations, or arrays of those basic types. How would Simulink know how to pass a memory address pointer to your block as an input? If your C code defines an array of C functions in appDiagGetFunc, can your block use an integer input for appID? Then Simulink can pass an integer to the C Caller block to select which function in appDiagGetFunc to call.
