-/*
- * Recursively builds a dentry tree from a directory tree on disk, outside the
- * WIM file.
- *
- * @root_ret: Place to return a pointer to the root of the dentry tree. Only
- * modified if successful. NULL if the file or directory was
- * excluded from capture.
- *
- * @root_disk_path: The path to the root of the directory tree on disk.
- *
- * @lookup_table: The lookup table for the WIM file. For each file added to the
- * dentry tree being built, an entry is added to the lookup table,
- * unless an identical stream is already in the lookup table.
- * These lookup table entries that are added point to the path of
- * the file on disk.
- *
- * @sd: Ignored. (Security data only captured in NTFS mode.)
- *
- * @capture_config:
- * Configuration for files to be excluded from capture.
- *
- * @add_flags: Bitwise or of WIMLIB_ADD_IMAGE_FLAG_*
- *
- * @extra_arg: Ignored. (Only used in NTFS mode.)
- *
- * @return: 0 on success, nonzero on failure. It is a failure if any of
- * the files cannot be `stat'ed, or if any of the needed
- * directories cannot be opened or read. Failure to add the files
- * to the WIM may still occur later when trying to actually read
- * the on-disk files during a call to wimlib_write() or
- * wimlib_overwrite().
