* implementetion of @c imagex for UNIX-based systems and an API to allow other
* programs to read, write, and mount WIM files. wimlib is comparable to
* Microsoft's WIMGAPI, but was designed independently and is not a clone of it.
- *
- * The main intended use of wimlib is to create customized images of Windows PE,
- * the Windows Preinstallation Environment, without having to rely on Windows.
- * Windows PE, which is the operating system that runs when you boot from the
- * Windows Vista or Windows 7 DVD, is a lightweight version of Windows that can
- * run entirely from memory. It can be used to install Windows from local media
- * or a network drive or perform maintenance.
- *
- * You can find Windows PE on the installation media for Windows Vista, Windows
- * 7, and Windows 8. The Windows PE image itself is a WIM file, @c
- * sources/boot.wim, on the ISO filesystem. Windows PE can also be found in the
- * Windows Automated Installation Kit (WAIK) inside the @c WinPE.cab file, which
- * you can extract if you install the @c cabextract program.
*
* \section format WIM files
*
* could do things like have 5 different versions of Windows that are almost
* exactly the same.
*
- * WIM files may contain a integrity table. The integrity table, if it exists,
- * is located at the end of the WIM file and contains SHA1 message digests of
- * 10MB chunks of the WIM.
- *
* Microsoft provides documentation for the WIM file format, XPRESS compression
- * format, and LZX compression format. However, there are errors and omissions
- * in some places in their documentation.
+ * format, and LZX compression format. The XPRESS documentation is acceptable,
+ * but the LZX documentation is not entirely correct, and the WIM documentation
+ * itself is very incomplete and is of unacceptable quality.
+ *
+ * A WIM file may be either stand-alone or split into multiple parts.
+ *
+ * \section winpe Windows PE
+ *
+ * A major use for this library is to create customized images of Windows PE, the
+ * Windows Preinstallation Environment, without having to rely on Windows. Windows
+ * PE is a lightweight version of Windows that can run entirely from memory and can
+ * be used to install Windows from local media or a network drive or perform
+ * maintenance. Windows PE is the operating system that runs when you boot from
+ * the Windows installation media.
+ *
+ * You can find Windows PE on the installation DVD for Windows Vista, Windows 7,
+ * or Windows 8, in the file @c sources/boot.wim. Windows PE can also be found
+ * in the Windows Automated Installation Kit (WAIK), which is free to download
+ * from Microsoft, inside the @c WinPE.cab file, which you can extract if you
+ * install either the @c cabextract or @c p7zip programs.
+ *
+ * In addition, Windows installations and recovery partitions frequently contain a
+ * WIM containing an image of the Windows Recovery Environment, which is similar to
+ * Windows PE.
+ *
+ * \section ntfs NTFS support
+ *
+ * As of version 1.0.0, wimlib supports capturing and applying images directly
+ * to NTFS volumes. This was made possible with the help of libntfs-3g from the
+ * NTFS-3g project. This feature supports capturing and restoring NTFS-specific
+ * data such as security descriptors, alternate data streams, and reparse point
+ * data.
+
+ * The code for NTFS image capture and image application is complete enough that
+ * it is possible to apply an image from the "install.wim" contained in recent
+ * Windows installation media (Vista, Windows 7, or Windows 8) directly to a
+ * NTFS volume, and then boot Windows from it after preparing the Boot
+ * Configuration Data. In addition, a Windows installation can be captured (or
+ * backed up) into a WIM file, and then re-applied later.
*
* \section starting Getting Started
*
* wimlib uses the GNU autotools, so it should be easy to install with
- * <code>configure && make && sudo make install</code>, provided that you have
- * @c libxml2 and @c libfuse installed. To use wimlib in a program after
- * installing it, include @c wimlib.h and link your program with @c -lwim.
+ * <code>configure && make && sudo make install</code>; however, please see the
+ * README for more information about installing it. To use wimlib in a program
+ * after installing it, include @c wimlib.h and link your program with @c -lwim.
*
- * wimlib wraps up a WIM file in an opaque ::WIMStruct structure.
+ * wimlib wraps up a WIM file in an opaque ::WIMStruct structure. A ::WIMStruct
+ * may represent either a stand-alone WIM or one part of a split WIM.
*
* All functions in wimlib's public API are prefixed with @c wimlib. Most
* return an integer error code on failure. Use wimlib_get_error_string() to
* get a string that describes an error code. wimlib also can print error
* messages itself when an error happens, and these may be more informative than
- * the error code; to enable this, call wimlib_set_print_errors().
+ * the error code; to enable this, call wimlib_set_print_errors(). Please note
+ * that this is for convenience only, and some errors can occur without a
+ * message being printed.
*
* wimlib is thread-safe as long as different ::WIMStruct's are used, with the
* following exceptions: wimlib_set_print_errors() and
*
* To add an image to a WIM file from a directory tree on your filesystem, call
* wimlib_add_image(). This can be done with a ::WIMStruct gotten from
- * wimlib_open_wim() or from wimlib_create_new_wim().
+ * wimlib_open_wim() or from wimlib_create_new_wim(). Alternatively, if you
+ * want to capture a WIM image directly from a NTFS volume while preserving
+ * NTFS-specific data such as security descriptors, call
+ * wimlib_add_image_from_ntfs_volume() instead.
*
- * To extract an image from a WIM file, call wimlib_set_output_dir() to set the
- * output directory, then call wimlib_extract_image().
+ * To extract an image from a WIM file, call wimlib_extract_image().
+ * Alternatively, if you want to apply a WIM image directly to a NTFS volume
+ * while setting NTFS-specific data such as security descriptors, call
+ * wimlib_apply_image_to_ntfs_volume().
+ *
+ * The NTFS functions will fail if wimlib was compiled with the
+ * <code>--without-ntfs-3g</code> flag.
*
* wimlib supports mounting WIM files either read-only or read-write. Mounting
* is done using wimlib_mount() and unmounting is done using wimlib_unmount().
* @c programs/imagex.c in wimlib's source tree.
*
* wimlib supports custom memory allocators; use wimlib_set_memory_allocator()
- * for this.
+ * for this. However, if wimlib calls into @c libntfs-3g, the custom memory
+ * allocator may not be used.
*
* \section imagex imagex
*
*
* While wimlib supports the main features of WIM files, wimlib currently has
* the following limitations:
- * - wimlib does not support modifying or creating "security data", which
- * describes the access rights of the files in the WIM. This data is very
- * Windows-specific, and it would be difficult to do anything with it.
- * Microsoft's software can still read a WIM without security data, including
- * a boot.wim for Windows PE, but <b>do not expect to be able to use wimlib to
- * image a Windows installation and preserve file attributes</b>. However, by
- * default, wimlib will preserve security data for existing WIMs.
- * - There is no way to directly extract or mount split WIMs.
- * - There is not yet any code to verify that there are no collisions between
- * different files that happen to have the same SHA1 message digest.
- * This is extremely unlikely, but could result in something bad such as a
- * file going missing.
- * - Alternate stream entries for directory entries are ignored.
- * - Different versions of the WIM file format, if they even exist, are
- * unsupported. Let me know if you notice WIM files with a different version.
- * - Chunk sizes other than 32768 are unsupported (except for uncompressed WIMs,
- * for which the chunk size field is ignored). As far as I can tell, other
- * chunk sizes are not used in compressed WIMs. Let me know if you find a WIM
- * file with a different chunk size.
+ * - Different versions of the WIM file format are unsupported. There is one
+ * different version of the format from development versions of Windows Vista,
+ * but I'm not planning to support it.
+ * - Compressed resource chunk sizes other than 32768 are unsupported (except for
+ * uncompressed WIMs, for which the chunk size field is ignored). As far as I
+ * can tell, other chunk sizes are not used in compressed WIMs. Let me know
+ * if you find a WIM file with a different chunk size.
* - wimlib does not provide a clone of the @b PEImg tool that allows you to
* make certain Windows-specific modifications to a Windows PE image, such as
* adding a driver or Windows component. Such a tool could conceivably be
* can implement this if requested, but I intend the FUSE mount feature to be
* used for this purpose, as it is easy to do these things in whatever way you
* want after the image is mounted.
- *
- * Currently, Microsoft's @a image.exe can create slightly smaller WIM files
- * than wimlib when using maximum (LZX) compression because it knows how to
- * split up LZX compressed blocks, which is not yet implemented in wimlib.
- *
- * wimlib is experimental and likely contains bugs; use Microsoft's @a
- * imagex.exe if you want to make sure your WIM files are made "correctly".
