3 * @brief External header for wimlib.
5 * This file contains extensive comments for generating documentation with
6 * Doxygen. The built HTML documentation can be viewed at
7 * http://wimlib.sourceforge.net. Make sure to see the <a
8 * href="modules.html">Modules page</a> to make more sense of the declarations
15 * This is the documentation for the library interface of wimlib 1.7.2, a C
16 * library for creating, modifying, extracting, and mounting files in the
17 * Windows Imaging Format. This documentation is intended for developers only.
18 * If you have installed wimlib and want to know how to use the @b wimlib-imagex
19 * program, please see the manual pages and also the <a
20 * href="http://sourceforge.net/p/wimlib/code/ci/master/tree/README">README
23 * @section sec_installing Installing
27 * Download the source code from <a
28 * href="http://sourceforge.net/projects/wimlib/files">http://sourceforge.net/projects/wimlib/files</a>.
29 * Install the library by running <c>configure && make && sudo make install</c>.
30 * See the README for information about configuration options. To use wimlib in
31 * your program after installing it, include wimlib.h and link your program with
36 * Download the Windows binary distribution with the appropriate architecture
37 * (i686 or x86_64 --- also called "x86" and "amd64" respectively) from <a
38 * href="http://sourceforge.net/projects/wimlib/files">http://sourceforge.net/projects/wimlib/files</a>.
39 * Link your program with the libwim-15.dll file. Make sure to also download
40 * the source code so you can get wimlib.h, as it is not included in the binary
41 * distribution. If you need to access the DLL from other programming
42 * languages, note that the calling convention is "cdecl".
44 * @section sec_examples Examples
46 * Several examples are located in the <a
47 * href="http://sourceforge.net/p/wimlib/code/ci/master/tree/examples">examples</a>
48 * directory of the source distribution.
50 * There is also the <a
51 * href="http://sourceforge.net/p/wimlib/code/ci/master/tree/programs/imagex.c">
52 * source code of <b>wimlib-imagex</b></a>, which is complicated but uses most
53 * capabilities of wimlib.
55 * @section backwards_compatibility Backwards Compatibility
57 * New releases of wimlib are intended to be API/ABI compatible with old
58 * releases, except when the libtool "age" is reset. This most recently
59 * occurred for the v1.4.0 (libwim7), v1.5.0 (libwim9), and v1.7.0 (libwim15)
60 * releases. However, the library is becoming increasingly stable, and the goal
61 * is to maintain the current API/ABI for as long as possible unless there is a
62 * strong reason not to. Even for the v1.7.0 release (libwim15), the changes
63 * were fairly limited.
65 * As with any other library, applications should not rely on internal
66 * implementation details that may be subject to change.
68 * @section sec_basic_wim_handling_concepts Basic WIM handling concepts
70 * wimlib wraps up a WIM file in an opaque ::WIMStruct structure. There are
71 * two ways to create such a structure: wimlib_open_wim(), which opens a WIM
72 * file and creates a ::WIMStruct representing it, and wimlib_create_new_wim(),
73 * which creates a new ::WIMStruct that initially contains no images and does
74 * not yet have a backing on-disk file. See @ref G_creating_and_opening_wims
77 * A WIM file, represented by a ::WIMStruct, contains zero or more images.
78 * Images can be extracted (or "applied") using wimlib_extract_image(), added
79 * (or "captured" or "appended") using wimlib_add_image(), deleted using
80 * wimlib_delete_image(), exported using wimlib_export_image(), and updated or
81 * modified using wimlib_update_image(). However, changes made to a WIM
82 * represented by a ::WIMStruct have no persistent effect until the WIM is
83 * actually written to an on-disk file. This can be done using wimlib_write(),
84 * but if the WIM was originally opened using wimlib_open_wim(), then
85 * wimlib_overwrite() can be used instead. See @ref G_extracting_wims, @ref
86 * G_modifying_wims, and @ref G_writing_and_overwriting_wims for more details.
88 * Note that with this ::WIMStruct abstraction, performing many tasks on WIM
89 * files is a multi-step process. For example, to add, or "append" an image to
90 * an existing stand-alone WIM file in a way similar to <b>wimlib-imagex
91 * append</b>, you must call the following functions:
93 * 1. wimlib_open_wim()
94 * 2. wimlib_add_image()
95 * 3. wimlib_overwrite()
97 * This design is very much on purpose as it makes the library more useful in
98 * general by allowing functions to be composed in different ways. For example,
99 * you can make multiple changes to a WIM and commit them all to the underlying
100 * file in only one overwrite operation, which is more efficient.
102 * Note: before calling any other function declared in wimlib.h,
103 * wimlib_global_init() can (and in some cases, must) be called. See its
104 * documentation for more details.
106 * @section sec_cleaning_up Cleaning up
108 * After you are done with any ::WIMStruct, you can call wimlib_free() to free
109 * all resources associated with it. Also, when you are completely done with
110 * using wimlib in your program, you can call wimlib_global_cleanup() to free
111 * any other resources allocated by the library.
113 * @section sec_error_handling Error Handling
115 * Most functions in wimlib return 0 on success and a positive error code on
116 * failure. Use wimlib_get_error_string() to get a string that describes an
117 * error code. wimlib also can print error messages to standard error itself
118 * when an error happens, and these may be more informative than the error code;
119 * to enable this, call wimlib_set_print_errors(). Please note that this is for
120 * convenience only, and some errors can occur without a message being printed.
121 * Currently, error messages and strings (as well as all documentation, for that
122 * matter) are only available in English.
124 * @section sec_encodings Locales and character encodings
126 * To support Windows as well as UNIX-like systems, wimlib's API typically takes
127 * and returns strings of ::wimlib_tchar, which are in a platform-dependent
130 * On Windows, each ::wimlib_tchar is 2 bytes and is the same as a "wchar_t",
131 * and the encoding is UTF-16LE.
133 * On UNIX-like systems, each ::wimlib_tchar is 1 byte and is simply a "char",
134 * and the encoding is the locale-dependent multibyte encoding. I recommend you
135 * set your locale to a UTF-8 capable locale to avoid any issues. Also, by
136 * default, wimlib on UNIX will assume the locale is UTF-8 capable unless you
137 * call wimlib_global_init() after having set your desired locale.

148 * See @ref G_progress.
150 * @subsection subsec_non_standalone_wims Non-standalone WIMs
152 * See @ref G_nonstandalone_wims.
154 * @subsection subsec_pipable_wims Pipable WIMs
156 * wimlib supports a special "pipable" WIM format which unfortunately is @b not
157 * compatible with Microsoft's software. To create a pipable WIM, call
158 * wimlib_write(), wimlib_write_to_fd(), or wimlib_overwrite() with
159 * ::WIMLIB_WRITE_FLAG_PIPABLE specified. Pipable WIMs are pipable in both
160 * directions, so wimlib_write_to_fd() can be used to write a pipable WIM to a
161 * pipe, and wimlib_extract_image_from_pipe() can be used to apply an image from
162 * a pipable WIM. wimlib can also transparently open and operate on pipable WIM
163 * s using a seekable file descriptor using the regular function calls (e.g.
164 * wimlib_open_wim(), wimlib_extract_image()).
166 * See the documentation for the <b>--pipable</b> flag of <b>wimlib-imagex
167 * capture</b> for more information about pipable WIMs.
169 * @subsection subsec_thread_safety Thread Safety
171 * wimlib is thread-safe, with the following exceptions:
172 * - Different threads cannot operate on the same ::WIMStruct at the same time;
173 * they must use different ::WIMStruct's.
174 * - You must call wimlib_global_init() in one thread before calling any other
176 * - wimlib_set_print_errors() and wimlib_set_memory_allocator() both apply globally.
177 * - wimlib_mount_image(), while it can be used to mount multiple WIMs
178 * concurrently in the same process, will daemonize the entire process when it
179 * does so for the first time. This includes changing the working directory
180 * to the root directory.
182 * @subsection subsec_limitations Limitations
184 * This section documents some technical limitations of wimlib not already
185 * documented in the man page for @b wimlib-imagex.
187 * - The old WIM format from Vista pre-releases is not supported.
188 * - wimlib does not provide a clone of the @b PEImg tool, or the @b DISM
189 * functionality other than that already present in @b ImageX, that allows you
190 * to make certain Windows-specific modifications to a Windows PE image, such
191 * as adding a driver or Windows component. Such a tool could be implemented
194 * @subsection more_info More information
196 * You are advised to read the README as well as the manual pages for
197 * <b>wimlib-imagex</b>, since not all relevant information is repeated here in
198 * the API documentation.

220 * @section sec_adding_images Capturing and adding WIM images
222 * As described in @ref sec_basic_wim_handling_concepts, capturing a new WIM or
223 * appending an image to an existing WIM is a multi-step process, but at its
224 * core is wimlib_add_image() or an equivalent function. Normally,
225 * wimlib_add_image() takes an on-disk directory tree and logically adds it to a
226 * ::WIMStruct as a new image. However, when supported by the build of the
227 * library, there is also a special NTFS volume capture mode (entered when
228 * ::WIMLIB_ADD_FLAG_NTFS is specified) that allows adding the image directly
229 * from an unmounted NTFS volume.
231 * Another function, wimlib_add_image_multisource() is also provided. It
232 * generalizes wimlib_add_image() to allow combining multiple files or directory
233 * trees into a single WIM image in a configurable way.
235 * For maximum customization of WIM image creation, it is also possible to add a
236 * completely empty WIM image with wimlib_add_empty_image(), then update it with
237 * wimlib_update_image(). (This is in fact what wimlib_add_image() and
238 * wimlib_add_image_multisource() do internally.)
240 * Note that some details of how image addition/capture works are documented
241 * more fully in the manual page for <b>wimlib-imagex capture</b>.
243 * @section sec_deleting_images Deleting WIM images
245 * wimlib_delete_image() can delete an image from a ::WIMStruct. But as usual,
246 * wimlib_write() or wimlib_overwrite() must be called to cause the changes to
247 * be made persistent in an on-disk WIM file.
249 * @section sec_exporting_images Exporting WIM images
251 * wimlib_export_image() can copy, or "export", an image from one WIM to
254 * @section sec_other_modifications Other modifications
256 * wimlib_update_image() can add, delete, and rename files in a WIM image.
258 * wimlib_set_image_name(), wimlib_set_image_descripton(), and
259 * wimlib_set_image_flags() can change other image metadata.
261 * wimlib_set_wim_info() can change information about the WIM file itself, such
265 /** @defgroup G_extracting_wims Extracting WIMs
267 * @brief Extract files, directories, and images from a WIM.
269 * wimlib_extract_image() extracts, or "applies", an image from a WIM,
270 * represented by a ::WIMStruct. This normally extracts the image to a
271 * directory, but when supported by the build of the library there is also a
272 * special NTFS volume extraction mode (entered when ::WIMLIB_EXTRACT_FLAG_NTFS
273 * is specified) that allows extracting a WIM image directly to an unmounted
274 * NTFS volume. Various other flags allow further customization of image
277 * wimlib_extract_paths() and wimlib_extract_pathlist() allow extracting a list
278 * of (possibly wildcard) paths from a WIM image.
280 * wimlib_extract_image_from_pipe() extracts an image from a pipable WIM sent
281 * over a pipe; see @ref subsec_pipable_wims.
283 * Some details of how WIM extraction works are documented more fully in the
284 * manual pages for <b>wimlib-imagex apply</b> and <b>wimlib-imagex extract</b>.
287 /** @defgroup G_mounting_wim_images Mounting WIM images
289 * @brief Mount and unmount WIM images.
291 * On Linux, wimlib supports mounting images from WIM files either read-only or
292 * read-write. To mount an image, call wimlib_mount_image(). To unmount an
293 * image, call wimlib_unmount_image(). Mounting can be done without root
294 * privileges because it is implemented using FUSE (Filesystem in Userspace).
296 * If wimlib is compiled using the <code>--without-fuse</code> flag, these
297 * functions will be available but will fail with ::WIMLIB_ERR_UNSUPPORTED.
299 * Note: if mounting is unsupported, wimlib still provides another way to modify
300 * a WIM image (wimlib_update_image()).
304 * @defgroup G_progress Progress Messages
306 * @brief Track the progress of long WIM operations.
308 * Library users can provide a progress function which will be called
309 * periodically during operations such as extracting a WIM image or writing a
310 * WIM image. A ::WIMStruct can have a progress function of type
311 * ::wimlib_progress_func_t associated with it by calling
312 * wimlib_register_progress_function() or by opening the ::WIMStruct using
313 * wimlib_open_wim_with_progress(). Once this is done, the progress function
314 * will be called automatically during many operations, such as
315 * wimlib_extract_image() and wimlib_write().
317 * Some functions that do not operate directly on a user-provided ::WIMStruct,
318 * such as wimlib_join(), also take the progress function directly using an
319 * extended version of the function, such as wimlib_join_with_progress().
321 * In wimlib v1.7.0 and later, progress functions are no longer just
322 * unidirectional. You can now return ::WIMLIB_PROGRESS_STATUS_ABORT to cause
323 * the current operation to be aborted. wimlib v1.7.0 also added the third
324 * argument to ::wimlib_progress_func_t, which is a user-supplied context.
327 /** @defgroup G_writing_and_overwriting_wims Writing and Overwriting WIMs
329 * @brief Write and overwrite on-disk WIM files.
331 * As described in @ref sec_basic_wim_handling_concepts, these functions are
332 * fundamental to the design of the library as they allow new or modified
333 * ::WIMStruct's to actually be written to on-disk files. Call wimlib_write()
334 * to write a new WIM file, or wimlib_overwrite() to persistently update an
338 /** @defgroup G_nonstandalone_wims Creating and handling non-standalone WIMs
340 * @brief Create and handle non-standalone WIMs, such as split and delta WIMs.
342 * Normally, a ::WIMStruct represents a WIM file, but there's a bit more to it
343 * than that. Normally, WIM files are "standalone". However, WIM files can
344 * also be arranged in non-standalone ways, such as a set of on-disk files that
345 * together form a single "split WIM" or "delta WIM". Such arrangements are
346 * fully supported by wimlib. However, as a result, in such cases a ::WIMStruct
347 * created from one of these on-disk files initially only partially represents
348 * the full WIM and needs to, in effect, be logically combined with other
349 * ::WIMStruct's before performing certain operations, such as extracting files
350 * with wimlib_extract_image() or wimlib_extract_paths(). This is done by
351 * calling wimlib_reference_resource_files() or wimlib_reference_resources().
353 * wimlib_write() can create delta WIMs as well as standalone WIMs, but a
354 * specialized function (wimlib_split()) is needed to create a split WIM.

2149 * Do not include streams already present in other WIMs. This flag can be used
2150 * to write a "delta" WIM after resources from the WIM on which the delta is to

2157 * Advises the library that for writes of all WIM images, all streams needed for
2158 * the WIM are already present (not in external resource WIMs) and their
2159 * reference counts are correct, so the code does not need to recalculate which
2160 * streams are referenced. This is for optimization purposes only, since with
2161 * this flag specified, the metadata resources may not need to be decompressed
2164 * wimlib_overwrite() will set this flag automatically.
2166 #define WIMLIB_WRITE_FLAG_STREAMS_OK 0x00000400
2169 * For wimlib_write(), retain the WIM's GUID instead of generating a new one.
2171 * wimlib_overwrite() sets this by default, since the WIM remains, logically,
2174 #define WIMLIB_WRITE_FLAG_RETAIN_GUID 0x00000800
2177 * When writing streams in the resulting WIM file, pack multiple streams into a
2178 * single compressed resource instead of compressing them independently. This
2179 * is also known as creating a "solid archive". This tends to produce a better
2180 * compression ratio at the cost of much slower random access.
2182 * WIM files created with this flag are only compatible with wimlib v1.6.0 or
2183 * later, WIMGAPI Windows 8 or later, and DISM Windows 8.1 or later. WIM files
2184 * created with this flag use a different version number in their header (3584
2185 * instead of 68864) and are also called "ESD files".
2187 * If this flag is passed to wimlib_overwrite(), any new data streams will be
2188 * written in solid mode. Use both ::WIMLIB_WRITE_FLAG_REBUILD and
2189 * ::WIMLIB_WRITE_FLAG_RECOMPRESS to force the entire WIM file be rebuilt with
2190 * all streams recompressed in solid mode.
2192 * Currently, new solid blocks will, by default, be written using LZMS
2193 * compression with 32 MiB (33554432 byte) chunks. Use
2194 * wimlib_set_output_pack_compression_type() and/or
2195 * wimlib_set_output_pack_chunk_size() to change this. This is independent of
2196 * the WIM's main compression type and chunk size; you can have a WIM that
2197 * nominally uses LZX compression and 32768 byte chunks but actually contains
2198 * LZMS-compressed solid blocks, for example. However, if including solid
2199 * blocks, I suggest that you set the WIM's main compression type to LZMS as
2200 * well, either by creating the WIM with
2201 * ::wimlib_create_new_wim(::WIMLIB_COMPRESSION_TYPE_LZMS, ...) or by calling
2202 * ::wimlib_set_output_compression_type(..., ::WIMLIB_COMPRESSION_TYPE_LZMS).
2204 * This flag will be set by default when writing or overwriting a WIM file that
2205 * either already contains packed streams, or has had packed streams exported
2206 * into it and the WIM's main compression type is LZMS.

4601 * compression, and 100 is high compression. This is not a percentage;
4602 * values above 100 are also valid.
