32 * \section intro Introduction
34 * This is the documentation for the library interface of wimlib 1.5.0, a C
35 * library for creating, modifying, extracting, and mounting files in the
36 * Windows Imaging Format. This documentation is intended for developers only.
37 * If you have installed wimlib and want to know how to use the @b wimlib-imagex
38 * program, please see the README file.
40 * \section starting Getting Started
42 * wimlib uses the GNU autotools, so, on UNIX systems, it should be easy to
43 * install with <code>configure && make && sudo make install</code>; however,
44 * please see the README for more information about installing it. To use
45 * wimlib in a program after installing it, include @c wimlib.h and link your
46 * program with @c -lwim.
48 * wimlib wraps up a WIM file in an opaque ::WIMStruct structure. A ::WIMStruct
49 * may represent either a stand-alone WIM or one part of a split WIM.
51 * All functions in wimlib's public API are prefixed with @c wimlib. Most
52 * return 0 on success and a positive error code on failure. Use
53 * wimlib_get_error_string() to get a string that describes an error code.
54 * wimlib also can print error messages itself when an error happens, and these
55 * may be more informative than the error code; to enable this, call
56 * wimlib_set_print_errors(). Please note that this is for convenience only,
57 * and some errors can occur without a message being printed.
59 * First before calling any other functions, you should call
60 * wimlib_global_init() to initialize the library.
62 * To open an existing WIM, use wimlib_open_wim().
64 * To create a new WIM that initially contains no images, use
65 * wimlib_create_new_wim().
67 * To add an image to a WIM file from a directory tree on your filesystem, call
68 * wimlib_add_image(). This can be done with a ::WIMStruct gotten from
69 * wimlib_open_wim() or from wimlib_create_new_wim(). On UNIX,
70 * wimlib_add_image() can also capture a WIM image directly from a block device
71 * containing a NTFS filesystem.
73 * To extract an image from a WIM file, call wimlib_extract_image(). This can
74 * be done either to a directory, or, on UNIX, directly to a block device
75 * containing a NTFS filesystem.
77 * To extract individual files or directories from a WIM image, rather than a
78 * full image, call wimlib_extract_files().
80 * To programatically make changes to a WIM image without mounting it, call
81 * wimlib_update_image().
83 * On UNIX, wimlib supports mounting WIM files either read-only or read-write.
84 * Mounting is done using wimlib_mount_image() and unmounting is done using
85 * wimlib_unmount_image(). Mounting can be done without root privileges because
86 * it is implemented using FUSE (Filesystem in Userspace). If wimlib is
87 * compiled with the <code>--without-fuse</code> flag, these functions will be
88 * available but will fail with ::WIMLIB_ERR_UNSUPPORTED.
90 * After creating or modifying a WIM file, you can write it to a file using
91 * wimlib_write(). Alternatively, if the WIM was originally read from a file
92 * (using wimlib_open_wim() rather than wimlib_create_new_wim()), you can use
93 * wimlib_overwrite() to overwrite the original file. Still alternatively, you
94 * can write a WIM directly to a file descriptor by calling wimlib_write_to_fd()
97 * wimlib supports a special "pipable" WIM format (which unfortunately is @b not
98 * compatible with Microsoft's software). To create a pipable WIM, call
99 * wimlib_write(), wimlib_write_to_fd(), or wimlib_overwrite() with
100 * ::WIMLIB_WRITE_FLAG_PIPABLE specified. Pipable WIMs are pipable in both
101 * directions, so wimlib_write_to_fd() can be used to write a pipable WIM to a
102 * pipe, and wimlib_extract_image_from_pipe() can be used to apply an image from
105 * Please note: merely by calling wimlib_add_image() or many of the other
106 * functions in this library that operate on ::WIMStruct's, you are @b not
107 * modifying the WIM file on disk. Changes are not saved until you explicitly
108 * call wimlib_write() or wimlib_overwrite().
110 * After you are done with the WIM file, use wimlib_free() to free all memory
111 * associated with a ::WIMStruct and close all files associated with it.
113 * When you are completely done with using wimlib in your program, you should
114 * call wimlib_global_cleanup().
116 * A number of functions take a pointer to a progress function of type
117 * ::wimlib_progress_func_t. This function will be called periodically during
118 * the WIM operation(s) to report on the progress of the operation (for example,
119 * how many bytes have been written so far).
121 * wimlib is thread-safe as long as different ::WIMStruct's are used, except for
122 * the following exceptions:
123 * - You must call wimlib_global_init() in one thread before calling any other
125 * - wimlib_set_print_errors() and wimlib_set_memory_allocator() both apply globally.
126 * race conditions with one-time allocations of memory.
127 * - wimlib_mount_image(), while it can be used to mount multiple WIMs
128 * concurrently in the same process, will daemonize the entire process when it
129 * does so for the first time. This includes changing the working directory
130 * to the root directory.
132 * \section encodings Locales and character encodings
134 * To support Windows as well as UNIX, wimlib's API typically takes and returns
135 * strings of ::wimlib_tchar, which are in a platform-dependent encoding.
137 * On Windows, each ::wimlib_tchar is 2 bytes and is the same as a "wchar_t",
138 * and the encoding is UTF-16LE.
140 * On UNIX, each ::wimlib_tchar is 1 byte and is simply a "char", and the
141 * encoding is the locale-dependent multibyte encoding. I recommend you set
142 * your locale to a UTF-8 capable locale to avoid any issues. Also, by default,
143 * wimlib on UNIX will assume the locale is UTF-8 capable unless you call
144 * wimlib_global_init() after having set your desired locale.
146 * \section Limitations
148 * This section documents some technical limitations of wimlib not already
149 * documented in the man page for @b wimlib-imagex.
151 * - The old WIM format from Vista pre-releases is not supported.
152 * - Compressed resource chunk sizes other than 32768 are not supported. This
153 * doesn't seem to be a real problem because the chunk size always seems to be
155 * - wimlib does not provide a clone of the @b PEImg tool, or the @b Dism
156 * functionality other than that already present in @b ImageX, that allows you
157 * to make certain Windows-specific modifications to a Windows PE image, such
158 * as adding a driver or Windows component. Such a tool possibly could be
159 * implemented on top of wimlib.

181 * Opaque structure that represents a WIM file. This is an in-memory structure
182 * and need not correspond to a specific on-disk file. However, a ::WIMStruct
183 * obtained from wimlib_open_wim() depends on the underlying on-disk WIM file
184 * continuing to exist so that data can be read from it as needed.
186 * Most functions in this library will work the same way regardless of whether a
187 * given ::WIMStruct was obtained through wimlib_open_wim() or
188 * wimlib_create_new_wim(). Exceptions are documented.
190 * Use wimlib_write() or wimlib_overwrite() to actually write an on-disk WIM
191 * file from a ::WIMStruct.

2468 * This only makes sense for ::WIMStruct's obtained from wimlib_open_wim()
2469 * rather than wimlib_create_new_wim().
2471 * There are two ways that a WIM may be overwritten. The first is to do a full
2472 * rebuild. In this mode, the new WIM is written to a temporary file and then
2473 * renamed to the original file after it is has been completely written. The
2474 * temporary file is made in the same directory as the original WIM file. A
2475 * full rebuild may take a while, but can be used even if images have been
2476 * modified or deleted, will produce a WIM with no holes, and has little chance
2477 * of unintentional data loss because the temporary WIM is fsync()ed before
2478 * being renamed to the original WIM.
2480 * The second way to overwrite a WIM is by appending to the end of it and
2481 * overwriting the header. This can be much faster than a full rebuild, but the
2482 * disadvantage is that some space will be wasted. Writing a WIM in this mode
2483 * begins with writing any new file resources *after* everything in the old WIM,
2484 * even though this will leave a hole where the old lookup table, XML data, and
2485 * integrity were. This is done so that the WIM remains valid even if the
2486 * operation is aborted mid-write. The WIM header is only overwritten at the
2487 * very last moment, and up until that point the WIM will be seen as the old
2490 * By default, wimlib_overwrite() does the append-style overwrite described
2491 * above, unless resources in the WIM are arranged in an unusual way or if
2492 * images have been deleted from the WIM. Use the flag
2493 * ::WIMLIB_WRITE_FLAG_REBUILD to explicitly request a full rebuild, and use the
2494 * ::WIMLIB_WRITE_FLAG_SOFT_DELETE to request the in-place overwrite even if
2495 * images have been deleted from the WIM.
2497 * In the temporary-file overwrite mode, no changes are made to the WIM on
2498 * failure, and the temporary file is deleted if possible. Abnormal termination
2499 * of the program will result in the temporary file being orphaned. In the
2500 * direct append mode, the WIM is truncated to the original length on failure;
2501 * and while abnormal termination of the program will result in extra data
2502 * appended to the original WIM, it should still be a valid WIM.
2504 * If this function completes successfully, no more functions should be called
2505 * on @a wim other than wimlib_free(). You must use wimlib_open_wim() to read
2506 * the WIM file anew.
