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
}

bye
