- * \section starting Getting Started
+ * \section installing_and_compiling Installing and Compiling
*
* wimlib uses the GNU autotools, so, on UNIX-like systems, it should be easy to
* install with <code>configure && make && sudo make install</code>; however,
- * please see the README for more information about installing it. To use
- * wimlib in a program after installing it, include @c wimlib.h and link your
- * program with @c -lwim.
+ * 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 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.
+ *
+ * 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.
+ *
+ * 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 <b>wimlib-imagex
+ * append</b>, 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 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 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.
*
- * wimlib wraps up a WIM file in an opaque ::WIMStruct structure. A ::WIMStruct
- * may represent either a stand-alone WIM or one part of a split WIM.
- *
- * All functions in wimlib's public API are prefixed with @c wimlib. Most
- * 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 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.
- *
- * First before calling any other functions, you should call
- * wimlib_global_init() to initialize the library.
+ * \section encodings Locales and character encodings
*
- * To open an existing WIM, use wimlib_open_wim().
+ * 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.
*
- * To create a new WIM that initially contains no images, use
- * wimlib_create_new_wim().
+ * On Windows, each ::wimlib_tchar is 2 bytes and is the same as a "wchar_t",
+ * and the encoding is UTF-16LE.
*
- * To add an image to a WIM file from a directory tree on your filesystem, call
- * wimlib_add_image(). This can be done with a ::WIMStruct gotten from
- * wimlib_open_wim() or from wimlib_create_new_wim(). On UNIX-like systems,
- * wimlib_add_image() can also capture a WIM image directly from a block device
- * containing a NTFS filesystem.
+ * 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.
*
- * To extract an image from a WIM file, call wimlib_extract_image(). This can
- * be done either to a directory, or, on UNIX-like systems, directly to a block
- * device containing a NTFS filesystem.
+ * \section advanced Additional information and features
+ *
+ * \subsection image_addition Image addition/capture
+ *
+ * As described in \ref 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 <b>wimlib-imagex capture</b>.
+ *
+ * \subsection extraction Image extraction/application
+ *
+ * wimlib_extract_image() extracts, or "applies", an image from a WIM
+ * (represented, as usual, 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.
+ *
+ * Another function, wimlib_extract_files(), is also provided. It can extract
+ * certain files or directories from a WIM image, instead of a full image.
+ *
+ * A third function, wimlib_extract_image_from_pipe(), allows an image to be
+ * extracted from a pipable WIM sent over a pipe; see \ref pipable_wims.
+ *
+ * Note that some details of how image extraction/application works are
+ * documented more fully in the manual pages for <b>wimlib-imagex apply</b> and
+ * <b>wimlib-imagex extract</b>.
+ *
+ * \subsection non_standalone_wims Non-standalone WIMs
+ *
+ * Earlier it was stated that a ::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_files().
+ * This is done by calling wimlib_reference_resource_files() or
+ * wimlib_reference_resources().
*
- * To extract individual files or directories from a WIM image, rather than a
- * full image, call wimlib_extract_files().
+ * wimlib_write() can create delta WIMs as well as standalone WIMs, but a
+ * specialized function (wimlib_split()) is needed to create a split WIM.
*
- * To programatically make changes to a WIM image without mounting it, call
- * wimlib_update_image().
+ * \subsection mounting_wim_images Mounting WIM images
*
* On UNIX-like systems supporting FUSE (such as Linux), wimlib supports
- * mounting WIM files either read-only or read-write. Mounting is done using
- * wimlib_mount_image() and unmounting is done using 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
- * <code>--without-fuse</code> flag, these functions will be available but will
- * fail with ::WIMLIB_ERR_UNSUPPORTED.
- *
- * After creating or modifying a WIM file, you can write it to a file using
- * wimlib_write(). Alternatively, if the WIM was originally read from a file
- * (using wimlib_open_wim() rather than wimlib_create_new_wim()), you can use
- * wimlib_overwrite() to overwrite the original file. Still alternatively, you
- * can write a WIM directly to a file descriptor by calling wimlib_write_to_fd()
- * instead.
- *
- * wimlib supports a special "pipable" WIM format (which unfortunately is @b not
- * compatible with Microsoft's software). To create a pipable WIM, call
+ * 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 <code>--without-fuse</code> 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().
+ *
+ * \subsection progress_functions Progress Functions
+ *
+ * When operating on large archives, operations such as extraction will
+ * naturally take a while to complete. Because of this and to improve the
+ * potential user-friendliness of library clients, a number of functions take a
+ * pointer to a progress function of type ::wimlib_progress_func_t. This
+ * function will be called periodically during the WIM operation(s) to report on
+ * the progress of the operation (for example, how many bytes have been written
+ * so far).
+ *
+ * \subsection 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
* s using a seekable file descriptor using the regular function calls (e.g.
* wimlib_open_wim(), wimlib_extract_image()).
*
- * Please note: merely by calling wimlib_add_image() or many of the other
- * functions in this library that operate on ::WIMStruct's, you are @b not
- * modifying the WIM file on disk. Changes are not saved until you explicitly
- * call wimlib_write() or wimlib_overwrite().
- *
- * After you are done with the WIM file, use wimlib_free() to free all memory
- * associated with a ::WIMStruct and close all files associated with it.
+ * See the documentation for the <b>--pipable</b> flag of <b>wimlib-imagex
+ * capture</b> for more information about pipable WIMs.
*
- * When you are completely done with using wimlib in your program, you should
- * call wimlib_global_cleanup().
+ * \subsection thread_safety Thread Safety
*
- * A number of functions take a pointer to a progress function of type
- * ::wimlib_progress_func_t. This function will be called periodically during
- * the WIM operation(s) to report on the progress of the operation (for example,
- * how many bytes have been written so far).
- *
- * wimlib is thread-safe as long as different ::WIMStruct's are used, except for
- * the following exceptions:
+ * 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.
* does so for the first time. This includes changing the working directory
* to the root directory.
*
- * \section 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.
