Otherwise, the location specifies the filesystem object. If it is relative, it the anchor is the file descriptor or the current working directory if the file descriptor is AT_FDCWD. + + There are two ways of managing the closing of file descriptors. One is to + treat AtLocation as an object that borrows file descriptors but never + closes them and taking care of closing them in some other way.
