32 * \section intro Introduction
34 * This is the documentation for the library interface of wimlib 1.2.6. If you
35 * have installed wimlib and want to know how to use the @c imagex program,
36 * please see the man pages instead.
38 * wimlib is a C library to read, write, and mount archive files in the Windows
39 * Imaging Format (WIM files). These files are normally created using the @c
40 * imagex.exe utility on Windows, but this library provides a free
41 * implementetion of @c imagex for UNIX-based systems and an API to allow other
42 * programs to read, write, and mount WIM files. wimlib is comparable to
43 * Microsoft's WIMGAPI, but was designed independently and is not a clone of it.
45 * \section format WIM files
47 * A <b>Windows Imaging (WIM)</b> file is an archive. Like some other archive
48 * formats such as ZIP, files in WIM archives may be compressed. WIM archives
49 * support two Microsoft-specific compression formats: @b LZX and @b XPRESS.
50 * Both are based on LZ77 and Huffman encoding, and both are supported by
53 * Unlike ZIP files, WIM files can contain multiple independent toplevel
54 * directory trees known as @a images. While each image has its own metadata,
55 * files are not duplicated for each image; instead, each file is included only
56 * once in the entire WIM. Microsoft did this so that in one WIM file, they
57 * could do things like have 5 different versions of Windows that are almost
60 * Microsoft provides documentation for the WIM file format, XPRESS compression
61 * format, and LZX compression format. The XPRESS documentation is acceptable,
62 * but the LZX documentation is not entirely correct, and the WIM documentation
63 * itself is incomplete.
65 * A WIM file may be either stand-alone or split into multiple parts.
67 * \section ntfs NTFS support
69 * As of version 1.0.0, wimlib supports capturing and applying images directly
70 * to NTFS volumes. This was made possible with the help of libntfs-3g from the
71 * NTFS-3g project. This feature supports capturing and restoring NTFS-specific
72 * data such as security descriptors, alternate data streams, and reparse point
75 * The code for NTFS image capture and image application is complete enough that
76 * it is possible to apply an image from the "install.wim" contained in recent
77 * Windows installation media (Vista, Windows 7, or Windows 8) directly to a
78 * NTFS volume, and then boot Windows from it after preparing the Boot
79 * Configuration Data. In addition, a Windows installation can be captured (or
80 * backed up) into a WIM file, and then re-applied later.
82 * \section winpe Windows PE
84 * A major use for this library is to create customized images of Windows PE, the
85 * Windows Preinstallation Environment, without having to rely on Windows. Windows
86 * PE is a lightweight version of Windows that can run entirely from memory and can
87 * be used to install Windows from local media or a network drive or perform
88 * maintenance. Windows PE is the operating system that runs when you boot from
89 * the Windows installation media.
91 * You can find Windows PE on the installation DVD for Windows Vista, Windows 7,
92 * or Windows 8, in the file @c sources/boot.wim. Windows PE can also be found
93 * in the Windows Automated Installation Kit (WAIK), which is free to download
94 * from Microsoft, inside the @c WinPE.cab file, which you can extract if you
95 * install either the @c cabextract or @c p7zip programs.
97 * In addition, Windows installations and recovery partitions frequently contain a
98 * WIM containing an image of the Windows Recovery Environment, which is similar to
101 * \section starting Getting Started
103 * wimlib uses the GNU autotools, so it should be easy to install with
104 * <code>configure && make && sudo make install</code>; however, please see the
105 * README for more information about installing it. To use wimlib in a program
106 * after installing it, include @c wimlib.h and link your program with @c -lwim.
108 * wimlib wraps up a WIM file in an opaque ::WIMStruct structure. A ::WIMStruct
109 * may represent either a stand-alone WIM or one part of a split WIM.
111 * All functions in wimlib's public API are prefixed with @c wimlib. Most
112 * return an integer error code on failure. Use wimlib_get_error_string() to
113 * get a string that describes an error code. wimlib also can print error
114 * messages itself when an error happens, and these may be more informative than
115 * the error code; to enable this, call wimlib_set_print_errors(). Please note
116 * that this is for convenience only, and some errors can occur without a
117 * message being printed.
119 * wimlib is thread-safe as long as different ::WIMStruct's are used, except for
120 * the following exceptions:
121 * - wimlib_set_print_errors() and wimlib_set_memory_allocator() both apply globally.
122 * - You also must call wimlib_global_init() in the main thread to avoid any
123 * race conditions with one-time allocations of memory.
124 * - wimlib_mount_image(), while it can be used to mount multiple WIMs
125 * concurrently in the same process, will daemonize the entire process when it
126 * does so for the first time. This includes changing the working directory
127 * to the root directory.
129 * To open an existing WIM, use wimlib_open_wim().
131 * To create a new WIM that initially contains no images, use
132 * wimlib_create_new_wim().
134 * To add an image to a WIM file from a directory tree on your filesystem, call
135 * wimlib_add_image(). This can be done with a ::WIMStruct gotten from
136 * wimlib_open_wim() or from wimlib_create_new_wim(). wimlib_add_image() can
137 * also capture a WIM image directly from a NTFS volume if you provide the
138 * ::WIMLIB_ADD_IMAGE_FLAG_NTFS flag, provided that wimlib was not compiled with
139 * the <code>--without-ntfs-3g</code> flag.
141 * To extract an image from a WIM file, call wimlib_extract_image(). You may
142 * extract an image either to a directory or directly to a NTFS volume, the
143 * latter of which will preserve NTFS-specific data such as security
146 * wimlib supports mounting WIM files either read-only or read-write. Mounting
147 * is done using wimlib_mount_image() and unmounting is done using
148 * wimlib_unmount_image(). Mounting can be done without root privileges because
149 * it is implemented using FUSE (Filesystem in Userspace). If wimlib is
150 * compiled with the <code>--without-fuse</code> flag, these functions will be
151 * available but will fail with ::WIMLIB_ERR_UNSUPPORTED.
153 * After creating or modifying a WIM file, you can write it to a file using
154 * wimlib_write(). Alternatively, if the WIM was originally read from a file
155 * (using wimlib_open_wim() rather than wimlib_create_new_wim()), you can use
156 * wimlib_overwrite() to overwrite the original file.
158 * Please note: merely by calling wimlib_add_image() or many of the other
159 * functions in this library that operate on ::WIMStruct's, you are @b not
160 * modifying the WIM file on disk. Changes are not saved until you explicitly
161 * call wimlib_write() or wimlib_overwrite().
163 * After you are done with the WIM file, use wimlib_free() to free all memory
164 * associated with a ::WIMStruct and close all files associated with it.
166 * A number of functions take a pointer to a progress function of type
167 * ::wimlib_progress_func_t. This function will be called periodically during
168 * the WIM operation(s) to report on the progress of the operation (for example,
169 * how many bytes have been written so far).
171 * \section imagex imagex
173 * wimlib comes with a command-line interface, the @b imagex program. It is
174 * documented with man pages. See its source code (@c programs/imagex.c in
175 * wimlib's source tree) for an example of how to use wimlib in your program.
177 * \section mkwinpeimg mkwinpeimg
179 * wimlib also comes with the <b>mkwinpeimg</b> script, which is documented in a
182 * \section Limitations
184 * While wimlib supports the main features of WIM files, wimlib currently has
185 * the following limitations:
186 * - wimlib cannot be used on MS-Windows.
187 * - There is no way to add, remove, modify, or extract specific files in a WIM
188 * without mounting it, other than by adding, removing, or extracting an
189 * entire image. The FUSE mount feature should be used for this purpose.
190 * - Currently, Microsoft's @a image.exe can create slightly smaller WIM files
191 * than wimlib when using maximum (LZX) compression because it knows how to
192 * split up LZX compressed blocks, which is not yet implemented in wimlib.
193 * - wimlib is experimental and likely contains bugs; use Microsoft's @a
194 * imagex.exe if you want to make sure your WIM files are made "correctly".
195 * - The old WIM format from Vista pre-releases is not supported.
196 * - Compressed resource chunk sizes other than 32768 are not supported,
197 * although this doesn't seem to be a problem because the chunk size always
198 * seems to be this value.
199 * - wimlib does not provide a clone of the @b PEImg tool that allows you to
200 * make certain Windows-specific modifications to a Windows PE image, such as
201 * adding a driver or Windows component. Such a tool could conceivably be
202 * implemented on top of wimlib, although it likely would be hard to implement
203 * because it would have to do very Windows-specific things such as
204 * manipulating the driver store. wimlib does provide the @b mkwinpeimg
205 * script for a similar purpose, however. With regards to adding drivers to
206 * Windows PE, you have the option of putting them anywhere in the Windows PE
207 * image, then loading them after boot using @b drvload.exe.

1608 * Overwrites the file that the WIM was originally read from, with changes made.
1609 * This only makes sense for ::WIMStruct's obtained from wimlib_open_wim()
1610 * rather than wimlib_create_new_wim().
1612 * There are two ways that a WIM may be overwritten. The first is to do a full
1613 * rebuild. In this mode, the new WIM is written to a temporary file and then
1614 * renamed to the original file after it is has been completely written. The
1615 * temporary file is made in the same directory as the original WIM file. A
1616 * full rebuild may take a while, but can be used even if images have been
1617 * modified or deleted, will produce a WIM with no holes, and has little chance
1618 * of unintentional data loss because the temporary WIM is fsync()ed before
1619 * being renamed to the original WIM.
1621 * The second way to overwrite a WIM is by appending to the end of it and
1622 * overwriting the header. This can be much faster than a full rebuild, but it
1623 * only works if the only operations on the WIM have been to change the header
1624 * and/or XML data, or to add new images. Writing a WIM in this mode begins
1625 * with writing any new file resources *after* everything in the old WIM, even
1626 * though this will leave a hole where the old lookup table, XML data, and
1627 * integrity were. This is done so that the WIM remains valid even if the
1628 * operation is aborted mid-write. The WIM header is only overwritten at the
1629 * very last moment, and up until that point the WIM will be seen as the old
1632 * By default, the overwrite mode is determine automatically based on the past
1633 * operations performed on the ::WIMStruct. Use the flag
1634 * ::WIMLIB_WRITE_FLAG_REBUILD to explicitly request a full rebuild, and use the
1635 * ::WIMLIB_WRITE_FLAG_SOFT_DELETE to request the in-place overwrite even if
1636 * images have been deleted from the WIM.
1638 * In the temporary-file overwrite mode, no changes are made to the WIM on
1639 * failure, and the temporary file is deleted if possible. Abnormal termination
1640 * of the program will result in the temporary file being orphaned. In the
1641 * direct append mode, the WIM is truncated to the original length on failure;
1642 * and while abnormal termination of the program will result in extra data
1643 * appended to the original WIM, it should still be a valid WIM.
