how to generate code int16 foo(uint16 a,int16* b) prototype

I need to implement int16 foo(uint16 a,int16* b) {a=&b;} in simulink. how to implement and generate the code as int16 foo(uint16 a,int16* b) {a=&b;}

[Guillaume]

int16 foo(uint16 a,int16* b) {a=&b;}

The function declaration looks like C code, but the function body is not valid (it does not assign anything to the return value) and is also pointless as it assign the address of pointer to a local variable that immediately goes out of scope. That's assuming you even can assign a pointer to an uint16 (which would require a 16-bit processor).

And is a really meant to be a pointer to a pointer to an int16?

Thanks for your valuable answer,but how to generate code with prototype 'int16 foo(uint16 a,int16* b)' ?
