This documentation is intended for developers only. * If you have installed wimlib and want to know how to use the @b wimlib-imagex * program, please see the README file or manual pages. * * @section sec_installing_and_compiling Installing and Compiling * * wimlib uses the GNU autotools, so, on UNIX-like systems, it should be easy to * install with configure && make && sudo make install; however, * please see the README for more information about installing it. * * To use wimlib in your program after installing it, include wimlib.h and link * your program with @c -lwim. * * As of wimlib 1.5.0, wimlib.h is also compatible with C++. * * Note: before calling any other function declared in wimlib.h, * wimlib_global_init() can (and in some cases, must) be called. See its * documentation for more details. * * @section sec_basic_wim_handling_concepts Basic WIM handling concepts * * wimlib wraps up a WIM file in an opaque ::WIMStruct structure. There are * two ways to create such a structure: wimlib_open_wim(), which opens a WIM * file and creates a ::WIMStruct representing it, and wimlib_create_new_wim(), * which creates a new ::WIMStruct that initially contains no images and does * not yet have a backing on-disk file. See @ref G_creating_and_opening_wims * for more details. * * A WIM file, represented by a ::WIMStruct, contains zero or more images. * Images can be extracted (or "applied") using wimlib_extract_image(), added * (or "captured" or "appended") using wimlib_add_image(), deleted using * wimlib_delete_image(), exported using wimlib_export_image(), and updated or * modified using wimlib_update_image(). However, changes made to a WIM * represented by a ::WIMStruct have no persistent effect until the WIM is * actually written to an on-disk file. This can be done using wimlib_write(), * but if the WIM was originally opened using wimlib_open_wim(), then * wimlib_overwrite() can be used instead. See @ref G_extracting_wims, @ref * G_modifying_wims, and @ref G_writing_and_overwriting_wims for more details. * * Note that with this ::WIMStruct abstraction, performing many tasks on WIM * files is a multi-step process. For example, to add, or "append" an image to * an existing stand-alone WIM file in a way similar to wimlib-imagex * append, you must call the following functions: * * 1. wimlib_open_wim() * 2. wimlib_add_image() * 3. wimlib_overwrite() * * This design is very much on purpose as it makes the library more useful in * general by allowing functions to be composed in different ways. For example, * you can make multiple changes to a WIM and commit them all to the underlying * file in only one overwrite operation, which is more efficient. * * @section sec_cleaning_up Cleaning up * * After you are done with any ::WIMStruct, you can call wimlib_free() to free * all resources associated with it. Also, when you are completely done with * using wimlib in your program, you can call wimlib_global_cleanup() to free * any other resources allocated by the library. * * @section sec_error_handling Error Handling * * Most functions in wimlib return 0 on success and a positive error code on * failure. Use wimlib_get_error_string() to get a string that describes an * error code. wimlib also can print error messages to standard error itself * when an error happens, and these may be more informative than the error code; * to enable this, call wimlib_set_print_errors(). Please note that this is for * convenience only, and some errors can occur without a message being printed. * Currently, error messages and strings (as well as all documentation, for that * matter) are only available in English. * * @section sec_encodings Locales and character encodings * * To support Windows as well as UNIX-like systems, wimlib's API typically takes * and returns strings of ::wimlib_tchar, which are in a platform-dependent * encoding. * * On Windows, each ::wimlib_tchar is 2 bytes and is the same as a "wchar_t", * and the encoding is UTF-16LE. * * On UNIX-like systems, each ::wimlib_tchar is 1 byte and is simply a "char", * and the encoding is the locale-dependent multibyte encoding. I recommend you * set your locale to a UTF-8 capable locale to avoid any issues. Also, by * default, wimlib on UNIX will assume the locale is UTF-8 capable unless you * call wimlib_global_init() after having set your desired locale. * * @section sec_advanced Additional information and features * * * @subsection subsec_mounting_wim_images Mounting WIM images * * See @ref G_mounting_wim_images. * * @subsection subsec_progress_functions Progress Messages * * See @ref G_progress. * * @subsection subsec_non_standalone_wims Non-standalone WIMs * * See @ref G_nonstandalone_wims. * * @subsection subsec_pipable_wims Pipable WIMs * * wimlib supports a special "pipable" WIM format which unfortunately is @b not * compatible with Microsoft's software. To create a pipable WIM, call * wimlib_write(), wimlib_write_to_fd(), or wimlib_overwrite() with * ::WIMLIB_WRITE_FLAG_PIPABLE specified. Pipable WIMs are pipable in both * directions, so wimlib_write_to_fd() can be used to write a pipable WIM to a * pipe, and wimlib_extract_image_from_pipe() can be used to apply an image from * a pipable WIM. wimlib can also transparently open and operate on pipable WIM * s using a seekable file descriptor using the regular function calls (e.g. * wimlib_open_wim(), wimlib_extract_image()). * * See the documentation for the --pipable flag of wimlib-imagex * capture for more information about pipable WIMs. * * @subsection subsec_thread_safety Thread Safety * * wimlib is thread-safe, with the following exceptions: * - Different threads cannot operate on the same ::WIMStruct at the same time; * they must use different ::WIMStruct's. * - You must call wimlib_global_init() in one thread before calling any other * functions. * - wimlib_set_print_errors() and wimlib_set_memory_allocator() both apply globally. * - wimlib_mount_image(), while it can be used to mount multiple WIMs * concurrently in the same process, will daemonize the entire process when it * does so for the first time. This includes changing the working directory * to the root directory. * * @subsection subsec_limitations Limitations * * This section documents some technical limitations of wimlib not already * documented in the man page for @b wimlib-imagex. * * - The old WIM format from Vista pre-releases is not supported. * - wimlib does not provide a clone of the @b PEImg tool, or the @b DISM * functionality other than that already present in @b ImageX, that allows you * to make certain Windows-specific modifications to a Windows PE image, such * as adding a driver or Windows component. Such a tool could be implemented * on top of wimlib. * * @subsection more_info More information * * You are advised to read the README as well as the manual pages for * wimlib-imagex, since not all relevant information is repeated here in * the API documentation. */ /** @defgroup G_general General * * @brief Declarations and structures shared across the library. */ /** @defgroup G_creating_and_opening_wims Creating and Opening WIMs * * @brief Create new WIMs and open existing WIMs. */ /** @defgroup G_wim_information Retrieving WIM information and directory listings * * @brief Retrieve information about a WIM or WIM image. */ /** @defgroup G_modifying_wims Modifying WIMs * * @brief Make changes to a WIM. * * @section sec_adding_images Capturing and adding WIM images * * As described in @ref sec_basic_wim_handling_concepts, capturing a new WIM or * appending an image to an existing WIM is a multi-step process, but at its * core is wimlib_add_image() or an equivalent function. Normally, * wimlib_add_image() takes an on-disk directory tree and logically adds it to a * ::WIMStruct as a new image. However, when supported by the build of the * library, there is also a special NTFS volume capture mode (entered when * ::WIMLIB_ADD_FLAG_NTFS is specified) that allows adding the image directly * from an unmounted NTFS volume. * * Another function, wimlib_add_image_multisource() is also provided. It * generalizes wimlib_add_image() to allow combining multiple files or directory * trees into a single WIM image in a configurable way. * * For maximum customization of WIM image creation, it is also possible to add a * completely empty WIM image with wimlib_add_empty_image(), then update it with * wimlib_update_image(). (This is in fact what wimlib_add_image() and * wimlib_add_image_multisource() do internally.) * * Note that some details of how image addition/capture works are documented * more fully in the manual page for wimlib-imagex capture. * * @section sec_deleting_images Deleting WIM images * * wimlib_delete_image() can delete an image from a ::WIMStruct. But as usual, * wimlib_write() or wimlib_overwrite() must be called to cause the changes to * be made persistent in an on-disk WIM file. * * @section sec_exporting_images Exporting WIM images * * wimlib_export_image() can copy, or "export", an image from one WIM to * another. * * @section sec_other_modifications Other modifications * * wimlib_update_image() can add, delete, and rename files in a WIM image. * * wimlib_set_image_name(), wimlib_set_image_descripton(), and * wimlib_set_image_flags() can change other image metadata. * * wimlib_set_wim_info() can change information about the WIM file itself, such * as the boot index. */ /** @defgroup G_extracting_wims Extracting WIMs * * @brief Extract files, directories, and images from a WIM. * * wimlib_extract_image() extracts, or "applies", an image from a WIM, * represented by a ::WIMStruct. This normally extracts the image to a * directory, but when supported by the build of the library there is also a * special NTFS volume extraction mode (entered when ::WIMLIB_EXTRACT_FLAG_NTFS * is specified) that allows extracting a WIM image directly to an unmounted * NTFS volume. Various other flags allow further customization of image * extraction. * * wimlib_extract_paths() and wimlib_extract_pathlist() allow extracting a list * of (possibly wildcard) paths from a WIM image. * * wimlib_extract_image_from_pipe() extracts an image from a pipable WIM sent * over a pipe; see @ref subsec_pipable_wims. * * Some details of how WIM extraction works are documented more fully in the * manual pages for wimlib-imagex apply and wimlib-imagex extract. */ /** @defgroup G_mounting_wim_images Mounting WIM images * * @brief Mount and unmount WIM images. * * On UNIX-like systems supporting FUSE (such as Linux), wimlib supports * mounting images from WIM files either read-only or read-write. To mount an * image, call wimlib_mount_image(). To unmount an image, call * wimlib_unmount_image(). Mounting can be done without root privileges because * it is implemented using FUSE (Filesystem in Userspace). If wimlib is * compiled with the --without-fuse flag, these functions will be * available but will fail with ::WIMLIB_ERR_UNSUPPORTED. Note that mounting an * image read-write is an alternative to calling wimlib_update_image(). */ /** * @defgroup G_progress Progress Messages * * @brief Track the progress of long WIM operations. * * Library users can provide a progress function which will be called * periodically during operations such as extracting a WIM image or writing a * WIM image. A ::WIMStruct can have a progress function of type * ::wimlib_progress_func_t associated with it by calling * wimlib_register_progress_function() or by opening the ::WIMStruct using * wimlib_open_wim_with_progress(). Once this is done, the progress function * will be called automatically during many operations, such as * wimlib_extract_image() and wimlib_write(). * * Some functions that do not operate directly on a user-provided ::WIMStruct, * such as wimlib_join(), also take the progress function directly using an * extended version of the function, such as wimlib_join_with_progress(). * * In wimlib v1.6.3 and later, progress functions are no longer just * unidirectional. You can now return ::WIMLIB_PROGRESS_STATUS_ABORT to cause * the current operation to be aborted. wimlib v1.6.3 also added the third * argument to ::wimlib_progress_func_t, which is a user-supplied context. */ /** @defgroup G_writing_and_overwriting_wims Writing and Overwriting WIMs * * @brief Write and overwrite on-disk WIM files. * * As described in @ref sec_basic_wim_handling_concepts, these functions are * critical to the design of the library as they allow new or modified WIMs to * actually be written to on-disk files. Generally, wimlib_write() is the * function you need to call to write a new WIM file, and wimlib_overwrite() is * the function you need to call to persistently update an existing WIM file. */ /** @defgroup G_nonstandalone_wims Creating and handling non-standalone WIMs * * @brief Create and handle non-standalone WIMs, such as split and delta WIMs. * * Normally, ::WIMStruct represents a WIM file, but there's a bit more to it * than that. Normally, WIM files are "standalone". However, WIM files can * also be arranged in non-standalone ways, such as a set of on-disk files that * together form a single "split WIM" or "delta WIM". Such arrangements are * fully supported by wimlib. However, as a result, in such cases a ::WIMStruct * created from one of these on-disk files initially only partially represents * the full WIM and needs to, in effect, be logically combined with other * ::WIMStruct's before performing certain operations, such as extracting files * with wimlib_extract_image() or wimlib_extract_paths(). This is done by * calling wimlib_reference_resource_files() or wimlib_reference_resources(). * * wimlib_write() can create delta WIMs as well as standalone WIMs, but a * specialized function (wimlib_split()) is needed to create a split WIM. */ #ifndef _WIMLIB_H #define _WIMLIB_H #include #include #include #include #include /** @ingroup G_general * @{ */ /** Major version of the library (for example, the 1 in 1.2.5). */ #define WIMLIB_MAJOR_VERSION 1 /** Minor version of the library (for example, the 2 in 1.2.5). */ #define WIMLIB_MINOR_VERSION 6 /** Patch version of the library (for example, the 5 in 1.2.5). */ #define WIMLIB_PATCH_VERSION 3 #ifdef __cplusplus extern "C" { #endif /** @} */ /** @ingroup G_general * @{ */ /** * Opaque structure that represents a WIM file.
