[boost] Re: filesystem hard link question

It throws whenever BOOST_POSIX is not defined. It is just this (works with 1.30.0, don't know about 1.31.0):

void link( const path & from_file_ph, const path & to_file_ph ) { # ifdef BOOST_POSIX if(::link(from_file_ph.native_file_string().c_str(), to_file_ph.native_file_string().c_str()) != 0) # endif boost::throw_exception( filesystem_error( "boost::filesystem::symlink", from_file_ph, to_file_ph, fs::detail::system_error_code() ) ); }

Why is a runtime error better than a compile-time error in this case? -- Dave Abrahams Boost Consulting www.boost-consulting.com
