Hi,
it depends. Level-1 S-functions in MATLAB are just simple MATLAB functions. If you call with the correct input parameters, it will work. Level-2 S-functions in MATLAB or in C will be more difficult, since providing the correct input parameters will be more difficult (MATLAB) or hardly possible (C). Perhaps you could describe in more detail what you are trying to do/achieve.

Hmm, there is indeed not much to be done: the function header of an S-function looks like this:
[sys,x0,str,ts,simStateCompliance] = sfun(t,x,u,flag)
where t is Time, x is the state vector, u the input and flag a value what to compute. E.g. for computing the output function:
sys = sfun(0, [], 42.0, 2);
assuming that it is a function without continous or discrete states ...
