[Boost-users] boost filesystem temp_dir

Hello, I've found on the mailinglist a posting of Jeff Flinn (2010-10-12), that the Boost Filesystem gets a method for reading the temporary directory of the OS. The call should be boost::filesystem::temp_dir_path() I try to use the code with the 1.45 release, but I get compiler errors (not found). In the documentation I don't found anything else. If the code is inserted in the 1:45 version and how can I use it then? Thx Phil
