32 * \section intro Introduction
34 * This is the documentation for the library interface of wimlib 1.3.2. If you
35 * have installed wimlib and want to know how to use the @b wimlib-imagex
36 * program, please see the man pages instead. Also: the actual project page
37 * where you can download the source code for the library is at <a
38 * href="https://sourceforge.net/projects/wimlib">https://sourceforge.net/projects/wimlib</a>.
40 * wimlib is a C library to read, write, and mount archive files in the Windows
41 * Imaging Format (WIM files). These files are normally created using the
42 * ImageX (@a imagex.exe) utility on Windows, but this library provides a free
43 * implementation of ImageX for UNIX-based systems (and, since v1.3.0, for
44 * Windows systems) and an API to allow other programs to read, write, and mount
45 * WIM files. wimlib is comparable to Microsoft's WIMGAPI, but was designed
46 * independently and is not a clone of it.
48 * \section format WIM files
50 * A <b>Windows Imaging (WIM)</b> file is an archive. Like some other archive
51 * formats such as ZIP, files in WIM archives may be compressed. WIM archives
52 * support two Microsoft-specific compression formats: @b LZX and @b XPRESS.
53 * Both are based on LZ77 and Huffman encoding, and both are supported by
56 * Unlike ZIP files, WIM files can contain multiple independent toplevel
57 * directory trees known as @a images. While each image has its own metadata,
58 * files are not duplicated for each image; instead, each file is included only
59 * once in the entire WIM. Microsoft did this so that in one WIM file, they
60 * could do things like have 5 different versions of Windows that are almost
63 * Microsoft provides documentation for the WIM file format, XPRESS compression
64 * format, and LZX compression format. The XPRESS documentation is acceptable,
65 * but the LZX documentation is not entirely correct, and the WIM documentation
66 * itself is incomplete.
68 * A WIM file may be either stand-alone or split into multiple parts.
70 * \section ntfs NTFS support
72 * As of version 1.0.0, wimlib supports capturing and applying images directly
73 * to NTFS volumes. This was made possible with the help of libntfs-3g from the
74 * NTFS-3g project. This feature supports capturing and restoring NTFS-specific
75 * data such as security descriptors, alternate data streams, and reparse point
78 * The code for NTFS image capture and image application is complete enough that
79 * it is possible to apply an image from the "install.wim" contained in recent
80 * Windows installation media (Vista, Windows 7, or Windows 8) directly to a
81 * NTFS volume, and then boot Windows from it after preparing the Boot
82 * Configuration Data. In addition, a Windows installation can be captured (or
83 * backed up) into a WIM file, and then re-applied later.
85 * wimlib v1.3.0 and later also supports NTFS capture and apply in the native
86 * Windows build, which works slightly differently and relies on native Win32
87 * API calls rather than libntfs-3g.
89 * \section winpe Windows PE
91 * A major use for this library is to create customized images of Windows PE, the
92 * Windows Preinstallation Environment, without having to rely on Windows. Windows
93 * PE is a lightweight version of Windows that can run entirely from memory and can
94 * be used to install Windows from local media or a network drive or perform
95 * maintenance. Windows PE is the operating system that runs when you boot from
96 * the Windows installation media.
98 * You can find Windows PE on the installation DVD for Windows Vista, Windows 7,
99 * or Windows 8, in the file @c sources/boot.wim. Windows PE can also be found
100 * in the Windows Automated Installation Kit (WAIK), which is free to download
101 * from Microsoft, inside the @c WinPE.cab file, which you can extract if you
102 * install either the @c cabextract or @c p7zip programs.
104 * In addition, Windows installations and recovery partitions frequently contain a
105 * WIM containing an image of the Windows Recovery Environment, which is similar to
108 * \section starting Getting Started
110 * wimlib uses the GNU autotools, so it should be easy to install with
111 * <code>configure && make && sudo make install</code>; however, please see the
112 * README for more information about installing it. To use wimlib in a program
113 * after installing it, include @c wimlib.h and link your program with @c -lwim.
115 * wimlib wraps up a WIM file in an opaque ::WIMStruct structure. A ::WIMStruct
116 * may represent either a stand-alone WIM or one part of a split WIM.
118 * All functions in wimlib's public API are prefixed with @c wimlib. Most
119 * return an integer error code on failure. Use wimlib_get_error_string() to
120 * get a string that describes an error code. wimlib also can print error
121 * messages itself when an error happens, and these may be more informative than
122 * the error code; to enable this, call wimlib_set_print_errors(). Please note
123 * that this is for convenience only, and some errors can occur without a
124 * message being printed.
126 * wimlib is thread-safe as long as different ::WIMStruct's are used, except for
127 * the following exceptions:
128 * - wimlib_set_print_errors() and wimlib_set_memory_allocator() both apply globally.
129 * - You also must call wimlib_global_init() in the main thread to avoid any
130 * race conditions with one-time allocations of memory.
131 * - wimlib_mount_image(), while it can be used to mount multiple WIMs
132 * concurrently in the same process, will daemonize the entire process when it
133 * does so for the first time. This includes changing the working directory
134 * to the root directory.
136 * To open an existing WIM, use wimlib_open_wim().
138 * To create a new WIM that initially contains no images, use
139 * wimlib_create_new_wim().
141 * To add an image to a WIM file from a directory tree on your filesystem, call
142 * wimlib_add_image(). This can be done with a ::WIMStruct gotten from
143 * wimlib_open_wim() or from wimlib_create_new_wim(). wimlib_add_image() can
144 * also capture a WIM image directly from a NTFS volume if you provide the
145 * ::WIMLIB_ADD_IMAGE_FLAG_NTFS flag, provided that wimlib was not compiled with
146 * the <code>--without-ntfs-3g</code> flag.
148 * To extract an image from a WIM file, call wimlib_extract_image(). You may
149 * extract an image either to a directory or directly to a NTFS volume, the
150 * latter of which will preserve NTFS-specific data such as security
153 * wimlib supports mounting WIM files either read-only or read-write. Mounting
154 * is done using wimlib_mount_image() and unmounting is done using
155 * wimlib_unmount_image(). Mounting can be done without root privileges because
156 * it is implemented using FUSE (Filesystem in Userspace). If wimlib is
157 * compiled with the <code>--without-fuse</code> flag, these functions will be
158 * available but will fail with ::WIMLIB_ERR_UNSUPPORTED.
160 * After creating or modifying a WIM file, you can write it to a file using
161 * wimlib_write(). Alternatively, if the WIM was originally read from a file
162 * (using wimlib_open_wim() rather than wimlib_create_new_wim()), you can use
163 * wimlib_overwrite() to overwrite the original file.
165 * Please note: merely by calling wimlib_add_image() or many of the other
166 * functions in this library that operate on ::WIMStruct's, you are @b not
167 * modifying the WIM file on disk. Changes are not saved until you explicitly
168 * call wimlib_write() or wimlib_overwrite().
170 * After you are done with the WIM file, use wimlib_free() to free all memory
171 * associated with a ::WIMStruct and close all files associated with it.
173 * A number of functions take a pointer to a progress function of type
174 * ::wimlib_progress_func_t. This function will be called periodically during
175 * the WIM operation(s) to report on the progress of the operation (for example,
176 * how many bytes have been written so far).
178 * \section imagex wimlib-imagex
180 * wimlib comes with a command-line interface, the @b wimlib-imagex program. It
181 * is documented with man pages. This program was originally just called @b
182 * imagex, but has been changed to @b wimlib-imagex to avoid confusion with
183 * Microsoft's @a imagex.exe (which would otherwise have exactly the same
184 * filename on Windows).
186 * \section mkwinpeimg mkwinpeimg
188 * wimlib also comes with the <b>mkwinpeimg</b> script, which is documented in a
191 * \section encodings Locales and character encodings
193 * To support Windows as well as UNIX, wimlib's API typically takes and returns
194 * strings of "tchars", which are in a platform-dependent encoding.
196 * On Windows, each "tchar" is 2 bytes and is the same as a "wchar_t", and the
197 * encoding is UTF-16LE.
199 * On UNIX, each "tchar" is 1 byte and is simply a "char", and the encoding is
200 * the locale-dependent multibyte encoding. I recommend you set your locale to a
201 * UTF-8 capable locale to avoid any issues. Also, by default, wimlib on UNIX
202 * will assume the locale is UTF-8 capable unless you call wimlib_global_init()
203 * after having set your desired locale.
205 * \section Limitations
207 * While wimlib supports the main features of WIM files, wimlib currently has
208 * the following limitations:
209 * - There is no way to add, remove, modify, or extract specific files in a WIM
210 * without mounting it, other than by adding, removing, or extracting an
211 * entire image. The FUSE mount feature should be used for this purpose.
212 * - Currently, Microsoft's @a image.exe can create slightly smaller WIM files
213 * than wimlib when using maximum (LZX) compression because it knows how to
214 * split up LZX compressed blocks, which is not yet implemented in wimlib.
215 * - wimlib is experimental and likely contains bugs; use Microsoft's @a
216 * imagex.exe if you want to make sure your WIM files are made "correctly".
217 * - The old WIM format from Vista pre-releases is not supported.
218 * - Compressed resource chunk sizes other than 32768 are not supported,
219 * although this doesn't seem to be a problem because the chunk size always
220 * seems to be this value.
221 * - wimlib does not provide a clone of the @b PEImg tool that allows you to
222 * make certain Windows-specific modifications to a Windows PE image, such as
223 * adding a driver or Windows component. Such a tool could conceivably be
224 * implemented on top of wimlib, although it likely would be hard to implement
225 * because it would have to do very Windows-specific things such as
226 * manipulating the driver store. wimlib does provide the @b mkwinpeimg
227 * script for a similar purpose, however. With regards to adding drivers to
228 * Windows PE, you have the option of putting them anywhere in the Windows PE
229 * image, then loading them after boot using @b drvload.exe.
230 * - Although wimlib 1.3.0 and later can be used on Windows as well as UNIX, the
231 * Windows build has some limitations compared to the UNIX build.
232 * (The differences are documented better in the man pages for
233 * @b wimlib-imagex than here.)

1794 * Overwrites the file that the WIM was originally read from, with changes made.
1795 * This only makes sense for ::WIMStruct's obtained from wimlib_open_wim()
1796 * rather than wimlib_create_new_wim().
1798 * There are two ways that a WIM may be overwritten. The first is to do a full
1799 * rebuild. In this mode, the new WIM is written to a temporary file and then
1800 * renamed to the original file after it is has been completely written. The
1801 * temporary file is made in the same directory as the original WIM file. A
1802 * full rebuild may take a while, but can be used even if images have been
1803 * modified or deleted, will produce a WIM with no holes, and has little chance
1804 * of unintentional data loss because the temporary WIM is fsync()ed before
1805 * being renamed to the original WIM.
1807 * The second way to overwrite a WIM is by appending to the end of it and
1808 * overwriting the header. This can be much faster than a full rebuild, but it
1809 * only works if the only operations on the WIM have been to change the header
1810 * and/or XML data, or to add new images. Writing a WIM in this mode begins
1811 * with writing any new file resources *after* everything in the old WIM, even
1812 * though this will leave a hole where the old lookup table, XML data, and
1813 * integrity were. This is done so that the WIM remains valid even if the
1814 * operation is aborted mid-write. The WIM header is only overwritten at the
1815 * very last moment, and up until that point the WIM will be seen as the old
1818 * By default, the overwrite mode is determine automatically based on the past
1819 * operations performed on the ::WIMStruct. Use the flag
1820 * ::WIMLIB_WRITE_FLAG_REBUILD to explicitly request a full rebuild, and use the
1821 * ::WIMLIB_WRITE_FLAG_SOFT_DELETE to request the in-place overwrite even if
1822 * images have been deleted from the WIM.
1824 * In the temporary-file overwrite mode, no changes are made to the WIM on
1825 * failure, and the temporary file is deleted if possible. Abnormal termination
1826 * of the program will result in the temporary file being orphaned. In the
1827 * direct append mode, the WIM is truncated to the original length on failure;
1828 * and while abnormal termination of the program will result in extra data
1829 * appended to the original WIM, it should still be a valid WIM.
