MATLAB: How to connect a bus to an S-function generated using Legacy Code Tool in Simulink 7.4 (R2009b)

simulink

I have an S-function generated from a legacy C-function using the Legacy Code Tool (LCT). I need to connect a bus input to this S-function, and receive a bus output from it.

The attached zip file "1-BL1XX7.zip" contains a model "businputandoutput.mdl" that demonstrates how to feed a bus input and receive a bus output from an S-function generated using Legacy Code Tool. Apart from the .mdl file, the zip file also contains the following attachments:
 1. doubleIt.c:  Legacy C-function
 2. commonHeader.h:  Legacy header file to the C-function
 3. sfun_generate_script_double.m:  Script to generate S-function using Legacy Code Tool from the above two C files
 4. foo_data.mat:  The .mat file that defines the bus signal that is fed as input to the S-function
 5. ex_sfun_doubleit.c:  S-function generated from files (1) and (2) above, by executing the MATLAB script (3) above.
 6. ex_sfun_doubleit.mexw32:  MEX-file corresponding to the S-function (5) above.
