[Boost-users] [interprocess] file_mapping/mapped_region on empty file throws?

The following appears to throw an interprocess_exception with boost_1_44_0 compiled with MSVC8 running on windows XP. using namespace boost::interprocess; file_mapping fm("empty.txt", read_only); mapped_region mr( fm, read_only); Is there a reason I can't just get back a null address and zero size? I've wrapped this to get back a begin/end range and an empty range is a valid condition. Thanks, Jeff
