how do I call from simulink a C function with many pointer arguments, and read such values as well?

Hi, my software is partly based on simulink applications and part in C code. The simulink calls C functions that usually return 1 output.

Recently, I've got C functions (from another development team), which 'return' a number of pointers as arguments. Example:

u16 NewSystemFunction (u16 *arg_1, s32 *arg_2, u16 *arg_3);

The question is, how do I call NewSystemFunction from Simulink and read arg_1, arg_2, arg_3 values?

Thanks in advance

Maybe the following article is of help to you:

One hint: You need to set the language of the stateflow chart to C.
