34 * @section sec_intro Introduction
36 * This is the documentation for the library interface of wimlib 1.6.0, a C
37 * library for creating, modifying, extracting, and mounting files in the
38 * Windows Imaging Format. This documentation is intended for developers only.
39 * If you have installed wimlib and want to know how to use the @b wimlib-imagex
40 * program, please see the README file or manual pages.
42 * @section sec_installing_and_compiling Installing and Compiling
44 * wimlib uses the GNU autotools, so, on UNIX-like systems, it should be easy to
45 * install with <code>configure && make && sudo make install</code>; however,
46 * please see the README for more information about installing it.
48 * To use wimlib in your program after installing it, include wimlib.h and link
49 * your program with @c -lwim.
51 * As of wimlib 1.5.0, wimlib.h is also compatible with C++.
53 * Note: before calling any other function declared in wimlib.h,
54 * wimlib_global_init() can (and in some cases, must) be called. See its
55 * documentation for more details.
57 * @section sec_basic_wim_handling_concepts Basic WIM handling concepts
59 * wimlib wraps up a WIM file in an opaque ::WIMStruct structure. There are
60 * two ways to create such a structure: wimlib_open_wim(), which opens a WIM
61 * file and creates a ::WIMStruct representing it, and wimlib_create_new_wim(),
62 * which creates a new ::WIMStruct that initially contains no images and does
63 * not yet have a backing on-disk file. See @ref G_creating_and_opening_wims
66 * A WIM file, represented by a ::WIMStruct, contains zero or more images.
67 * Images can be extracted (or "applied") using wimlib_extract_image(), added
68 * (or "captured" or "appended") using wimlib_add_image(), deleted using
69 * wimlib_delete_image(), exported using wimlib_export_image(), and updated or
70 * modified using wimlib_update_image(). However, changes made to a WIM
71 * represented by a ::WIMStruct have no persistent effect until the WIM is
72 * actually written to an on-disk file. This can be done using wimlib_write(),
73 * but if the WIM was originally opened using wimlib_open_wim(), then
74 * wimlib_overwrite() can be used instead. See @ref G_extracting_wims, @ref
75 * G_modifying_wims, and @ref G_writing_and_overwriting_wims for more details.
77 * Note that with this ::WIMStruct abstraction, performing many tasks on WIM
78 * files is a multi-step process. For example, to add, or "append" an image to
79 * an existing stand-alone WIM file in a way similar to <b>wimlib-imagex
80 * append</b>, you must call the following functions:
82 * 1. wimlib_open_wim()
83 * 2. wimlib_add_image()
84 * 3. wimlib_overwrite()
86 * This design is very much on purpose as it makes the library more useful in
87 * general by allowing functions to be composed in different ways. For example,
88 * you can make multiple changes to a WIM and commit them all to the underlying
89 * file in only one overwrite operation, which is more efficient.
91 * @section sec_cleaning_up Cleaning up
93 * After you are done with any ::WIMStruct, you can call wimlib_free() to free
94 * all resources associated with it. Also, when you are completely done with
95 * using wimlib in your program, you can call wimlib_global_cleanup() to free
96 * any other resources allocated by the library.
98 * @section sec_error_handling Error Handling
100 * Most functions in wimlib return 0 on success and a positive error code on
101 * failure. Use wimlib_get_error_string() to get a string that describes an
102 * error code. wimlib also can print error messages to standard error itself
103 * when an error happens, and these may be more informative than the error code;
104 * to enable this, call wimlib_set_print_errors(). Please note that this is for
105 * convenience only, and some errors can occur without a message being printed.
106 * Currently, error messages and strings (as well as all documentation, for that
107 * matter) are only available in English.
109 * @section sec_encodings Locales and character encodings
111 * To support Windows as well as UNIX-like systems, wimlib's API typically takes
112 * and returns strings of ::wimlib_tchar, which are in a platform-dependent
115 * On Windows, each ::wimlib_tchar is 2 bytes and is the same as a "wchar_t",
116 * and the encoding is UTF-16LE.
118 * On UNIX-like systems, each ::wimlib_tchar is 1 byte and is simply a "char",
119 * and the encoding is the locale-dependent multibyte encoding. I recommend you
120 * set your locale to a UTF-8 capable locale to avoid any issues. Also, by
121 * default, wimlib on UNIX will assume the locale is UTF-8 capable unless you
122 * call wimlib_global_init() after having set your desired locale.
124 * @section sec_advanced Additional information and features
127 * @subsection subsec_mounting_wim_images Mounting WIM images
129 * See @ref G_mounting_wim_images.
131 * @subsection subsec_progress_functions Progress Messages
133 * See @ref G_progress.
135 * @subsection subsec_non_standalone_wims Non-standalone WIMs
137 * See @ref G_nonstandalone_wims.
139 * @subsection subsec_pipable_wims Pipable WIMs
141 * wimlib supports a special "pipable" WIM format which unfortunately is @b not
142 * compatible with Microsoft's software. To create a pipable WIM, call
143 * wimlib_write(), wimlib_write_to_fd(), or wimlib_overwrite() with
144 * ::WIMLIB_WRITE_FLAG_PIPABLE specified. Pipable WIMs are pipable in both
145 * directions, so wimlib_write_to_fd() can be used to write a pipable WIM to a
146 * pipe, and wimlib_extract_image_from_pipe() can be used to apply an image from
147 * a pipable WIM. wimlib can also transparently open and operate on pipable WIM
148 * s using a seekable file descriptor using the regular function calls (e.g.
149 * wimlib_open_wim(), wimlib_extract_image()).
151 * See the documentation for the <b>--pipable</b> flag of <b>wimlib-imagex
152 * capture</b> for more information about pipable WIMs.
154 * @subsection subsec_thread_safety Thread Safety
156 * wimlib is thread-safe, with the following exceptions:
157 * - Different threads cannot operate on the same ::WIMStruct at the same time;
158 * they must use different ::WIMStruct's.
159 * - You must call wimlib_global_init() in one thread before calling any other
161 * - wimlib_set_print_errors() and wimlib_set_memory_allocator() both apply globally.
162 * - wimlib_mount_image(), while it can be used to mount multiple WIMs
163 * concurrently in the same process, will daemonize the entire process when it
164 * does so for the first time. This includes changing the working directory
165 * to the root directory.
167 * @subsection subsec_limitations Limitations
169 * This section documents some technical limitations of wimlib not already
170 * documented in the man page for @b wimlib-imagex.
172 * - The old WIM format from Vista pre-releases is not supported.
173 * - wimlib does not provide a clone of the @b PEImg tool, or the @b Dism
174 * functionality other than that already present in @b ImageX, that allows you
175 * to make certain Windows-specific modifications to a Windows PE image, such
176 * as adding a driver or Windows component. Such a tool could be implemented
179 * @subsection more_info More information
181 * You are advised to read the README as well as the manual pages for
182 * <b>wimlib-imagex</b>, since not all relevant information is repeated here in
183 * the API documentation.

205 * @section sec_adding_images Capturing and adding WIM images
207 * As described in @ref sec_basic_wim_handling_concepts, capturing a new WIM or
208 * appending an image to an existing WIM is a multi-step process, but at its
209 * core is wimlib_add_image() or an equivalent function. Normally,
210 * wimlib_add_image() takes an on-disk directory tree and logically adds it to a
211 * ::WIMStruct as a new image. However, when supported by the build of the
212 * library, there is also a special NTFS volume capture mode (entered when
213 * ::WIMLIB_ADD_FLAG_NTFS is specified) that allows adding the image directly
214 * from an unmounted NTFS volume.
216 * Another function, wimlib_add_image_multisource() is also provided. It
217 * generalizes wimlib_add_image() to allow combining multiple files or directory
218 * trees into a single WIM image in a configurable way.
220 * For maximum customization of WIM image creation, it is also possible to add a
221 * completely empty WIM image with wimlib_add_empty_image(), then update it with
222 * wimlib_update_image(). (This is in fact what wimlib_add_image() and
223 * wimlib_add_image_multisource() do internally.)
225 * Note that some details of how image addition/capture works are documented
226 * more fully in the manual page for <b>wimlib-imagex capture</b>.
228 * @section sec_deleting_images Deleting WIM images
230 * wimlib_delete_image() can delete an image from a ::WIMStruct. But as usual,
231 * wimlib_write() or wimlib_overwrite() must be called to cause the changes to
232 * be made persistent in an on-disk WIM file.
234 * @section sec_exporting_images Exporting WIM images
236 * wimlib_export_image() can copy, or "export", an image from one WIM to
239 * @section sec_other_modifications Other modifications
241 * wimlib_update_image() can add, delete, and rename files in a WIM image.
243 * wimlib_set_image_name(), wimlib_set_image_descripton(), and
244 * wimlib_set_image_flags() can change other image metadata.
246 * wimlib_set_wim_info() can change information about the WIM file itself, such
250 /** @defgroup G_extracting_wims Extracting WIMs
252 * @brief Extract files, directories, and images from a WIM.
254 * wimlib_extract_image() extracts, or "applies", an image from a WIM
255 * (represented, as usual, by a ::WIMStruct). This normally extracts the image
256 * to a directory, but when supported by the build of the library there is also
257 * a special NTFS volume extraction mode (entered when
258 * ::WIMLIB_EXTRACT_FLAG_NTFS is specified) that allows extracting a WIM image
259 * directly to an unmounted NTFS volume. Various other flags allow further
260 * customization of image extraction.
262 * Another function, wimlib_extract_files(), is also provided. It can extract
263 * certain files or directories from a WIM image, instead of a full image.
265 * wimlib_extract_paths() and wimlib_extract_pathlist() allow extracting a set
266 * of paths from a WIM image in a manner that may be easier to use than
267 * wimlib_extract_files(), and also allow wildcard patterns.
269 * wimlib_extract_image_from_pipe() allows an image to be extracted from a
270 * pipable WIM sent over a pipe; see @ref subsec_pipable_wims.
272 * Note that some details of how image extraction/application works are
273 * documented more fully in the manual pages for <b>wimlib-imagex apply</b> and
274 * <b>wimlib-imagex extract</b>.
277 /** @defgroup G_mounting_wim_images Mounting WIM images
279 * @brief Mount and unmount WIM images.
281 * On UNIX-like systems supporting FUSE (such as Linux), wimlib supports
282 * mounting images from WIM files either read-only or read-write. To mount an
283 * image, call wimlib_mount_image(). To unmount an image, call
284 * wimlib_unmount_image(). Mounting can be done without root privileges because
285 * it is implemented using FUSE (Filesystem in Userspace). If wimlib is
286 * compiled with the <code>--without-fuse</code> flag, these functions will be
287 * available but will fail with ::WIMLIB_ERR_UNSUPPORTED. Note that mounting an
288 * image read-write is an alternative to calling wimlib_update_image().
291 /** @defgroup G_progress Progress Messages
293 * @brief Track the progress of long WIM operations.
295 * When operating on large archives, operations such as extraction will
296 * naturally take a while to complete. Because of this and to improve the
297 * potential user-friendliness of library clients, a number of functions take a
298 * pointer to a progress function of type ::wimlib_progress_func_t. This
299 * function will be called periodically during the WIM operation(s) to report on
300 * the progress of the operation (for example, how many bytes have been written
304 /** @defgroup G_writing_and_overwriting_wims Writing and Overwriting WIMs
306 * @brief Write and overwrite on-disk WIM files.
308 * As described in @ref sec_basic_wim_handling_concepts, these functions are
309 * critical to the design of the library as they allow new or modified WIMs to
310 * actually be written to on-disk files. Generally, wimlib_write() is the
311 * function you need to call to write a new WIM file, and wimlib_overwrite() is
312 * the function you need to call to persistently update an existing WIM file.
315 /** @defgroup G_nonstandalone_wims Creating and handling non-standalone WIMs
317 * @brief Create and handle non-standalone WIMs, such as split and delta WIMs.
319 * Normally, ::WIMStruct represents a WIM file, but there's a bit more to it
320 * than that. Normally, WIM files are "standalone". However, WIM files can
321 * also be arranged in non-standalone ways, such as a set of on-disk files that
322 * together form a single "split WIM" or "delta WIM". Such arrangements are
323 * fully supported by wimlib. However, as a result, in such cases a ::WIMStruct
324 * created from one of these on-disk files initially only partially represents
325 * the full WIM and needs to, in effect, be logically combined with other
326 * ::WIMStruct's before performing certain operations, such as extracting files
327 * with wimlib_extract_image() or wimlib_extract_files(). This is done by
328 * calling wimlib_reference_resource_files() or wimlib_reference_resources().
330 * wimlib_write() can create delta WIMs as well as standalone WIMs, but a
331 * specialized function (wimlib_split()) is needed to create a split WIM.

3006 * This only makes sense for ::WIMStruct's obtained from wimlib_open_wim()
3007 * rather than wimlib_create_new_wim().
3009 * There are two ways that a WIM may be overwritten. The first is to do a full
3010 * rebuild. In this mode, the new WIM is written to a temporary file and then
3011 * renamed to the original file after it is has been completely written. The
3012 * temporary file is made in the same directory as the original WIM file. A
3013 * full rebuild may take a while, but can be used even if images have been
3014 * modified or deleted, will produce a WIM with no holes, and has little chance
3015 * of unintentional data loss because the temporary WIM is fsync()ed before
3016 * being renamed to the original WIM.
3018 * The second way to overwrite a WIM is by appending to the end of it and
3019 * overwriting the header. This can be much faster than a full rebuild, but the
3020 * disadvantage is that some space will be wasted. Writing a WIM in this mode
3021 * begins with writing any new file resources *after* everything in the old WIM,
3022 * even though this will leave a hole where the old lookup table, XML data, and
3023 * integrity were. This is done so that the WIM remains valid even if the
3024 * operation is aborted mid-write. The WIM header is only overwritten at the
3025 * very last moment, and up until that point the WIM will be seen as the old
3028 * By default, wimlib_overwrite() does the append-style overwrite described
3029 * above, unless resources in the WIM are arranged in an unusual way or if
3030 * images have been deleted from the WIM. Use the flag
3031 * ::WIMLIB_WRITE_FLAG_REBUILD to explicitly request a full rebuild, and use the
3032 * ::WIMLIB_WRITE_FLAG_SOFT_DELETE to request the in-place overwrite even if
3033 * images have been deleted from the WIM.
3035 * In the temporary-file overwrite mode, no changes are made to the WIM on
3036 * failure, and the temporary file is deleted if possible. Abnormal termination
3037 * of the program will result in the temporary file being orphaned. In the
3038 * direct append mode, the WIM is truncated to the original length on failure;
3039 * and while abnormal termination of the program will result in extra data
3040 * appended to the original WIM, it should still be a valid WIM.
3042 * If this function completes successfully, no more functions should be called
