  Try:

with Interfaces.C;
procedure Main is

  procedure C_Print(Filename, Str : access Interfaces.C.Char;
                    Filename_Length, Str_Length: in Interfaces.C.Size_T);
  pragma Import(C, C_Print, "print_");

  procedure Print(Filename, Str : in String) is
    C_Filename: Interfaces.C.Char_Array := Interfaces.C.To_C(Filename);
    C_Str   : Interfaces.C.Char_Array := Interfaces.C.To_C(Str);
  begin
    C_Print(C_Filename(0)'Unchecked_Access, C_Str(0)'Unchecked_Access,
      Interfaces.C.Size_T(Filename'Length), Interfaces.C.Size_T(Str'Length));
  end Print;

begin
  Print("test.out", "Testing...");
end Main;
