this function in Mathematica would be:

xxx[s_Integer, y_Integer]:=Module[{Q},
    Q = s*y;
    Q
]


more generally:

type_t function( some_input )
{
   int local_var_1;
   double local_var_2;

   local_var_1=somefunction(some_input);
   local_var_2=somefunction(some_input);
   ...
   ...

   return(local_var_2);
}

wolud be:

function[someinput_]:=Module[{local1,local2),
   local1=somefunction[someInput];
   local2=somefunction[someInput];
   ...
   ...

   local2
}
