Boost C++ Libraries: Ticket #2817: boost::iostreams::file_descriptor::is_open() implemented incorrectly

anonymous — Mon, 02 Mar 2009 22:23:41 GMT

Oops, my previous code is missing a '-'. The code should read as follows:

#ifdef BOOST_IOSTREAMS_WINDOWS

bool is_open() const { return pimpl_->handle_ != reinterpret_cast<handle_type>(-1); }

#else

bool is_open() const { return pimpl_->handle_ != -1; }

#endif

I concur it's implemented incorrectly.

However, some functions on Windows return 0 instead of INVALID_HANDLE_VALUE, so I think it should be compared against both.

further (independent) discussion of this issue occurred on the devel list recently. see: http://thread.gmane.org/gmane.comp.lib.boost.devel/190541

status changed; resolution set

Looks like this was fixed in [46669].
