[boost] [iostreams]Re: Bug in mapped_file.cpp

Rory O'Connor wrote:

In the file \boost\libs\iostreams\src\mapped_file.cpp on line 126 there is a simple member function called mapped_file_source::is_open().

It was assuming that an invalid handle was 0 but that is not true for a Windows bulid.

I changed the function to the following:

bool mapped_file_source::is_open() const

{

#ifdef BOOST_IOSTREAMS_WINDOWS

return !!pimpl_ && pimpl_->handle_ != INVALID_HANDLE_VALUE;

#else

return !!pimpl_ && pimpl_->handle_ != 0;

#endif

}

I think the preferred approach is to log a bug in the bug tracker against the iostreams component at http://svn.boost.org/trac/boost/ Perhaps a little test case which demonstrates the error too.
