S-function level 2 Cell String Array

I am trying to read a cell string array in block mask parameter and use the strings of the array to generate code in .tlc file.

How do I read a cell string array mask parameter in a S function level 2 and pass to .tlc file? Say, a mask dialogue box parameter has a value like:

input= {'ab' 'c' 'def'}

How do I read "input" parameter in S function? Is there any function like:

ssWriteRTWStrVectParam(S, "input_names", utilGetstrParamAddr(0), 3)

which can be used to assign the parameter's ("input") value or address (pointer) of the variable "input_names"? How do I get access to each element of this "input_names" that has been sent to the .tlc file? Will the "%foreach" work in .tlc to have access to each of the element of this variable ("input_names")? Thanks.
