I have a char array baked into a struct (not a pointer), and I just
want a confirm that I do it the correct/intended way.

struct {
 uint8 Value;
 uint8 String[SIZE_OF_ARRAY];
} MyArray_t;

class MyArray_t < FFI::Struct
 layout  :Value,  :uint8,
         :String, [:uint8, SIZE_OF_ARRAY]
end

my_array_struct = MyArray_t.new
c_function(my_array_struct.pointer) #the c_function fills the char
array
str = my_array_struct[:String].to_s # is to_s the correct function to
retrieve a string? read_string doesn't work.

Thanks,
/D
