try {        boost::filesystem::create_directory ("C:\Program Files\hello123");      }      catch (const boost::filesystem::basic_filesystem_error& ) {        std::cerr << "Directory creation failed" << std::endl;      }

The above code crashes if user doesn't have root permission. I assume some exception is being thrown as catch (...) catches whatevers being thrown. The documentation says "Throws: basic_filesystem_error<Path> if  Effects fails for any reason other than because the directory already exists." The requested directory "C:\Program Files\hello123" doesn't exist, so I should have caught a boost::filesystem::basic_filesystem_error. Is this a known issue or am I the only one seeing this?

basic_filesystem_error<Path> is not the same as basic_filesystem_error as Path will be a boost::filesystem::path type.

Right. Changing to basic_filesystem_error<Path> worked. I see a lot of the examples just catch std::exception. thanks... Ciju

If in doubt, catch (std::exception &e) and inspect the type of e in the debugger. Regards -- Craig _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
