Generating a C s-function with legacy code with an array of buses as input

Hello everybody,

i am using the legacy_code to generate a C S-Function and now I need this s-function to get an array of buses. The s-function actually only call a c function defined as: void Fct( sBusStruct const* const p_Input[],...)

I basically need to define the output function of the s-function the same way or something like that. For the previous case, where I needed the s-function to receive only one bus and not an array of them, here is how I define the output functions using the legacy tool:

   lct_ip.OutputFcnSpec =...
          ['sDLLFCT_Outputs_wrapper(sBusStruct* u1[1])'];
  legacy_code('compile', lct_ip, OPTIONS);

Now I am not sure how to change that legacy_code declaration so that that wrapper s-function method will receive an array of buses. can anyone tell me , if this is possible or has already been done!?

Best Regards and Thanks in Advance

Armand ps: using Matlab R2013b 32bits
