+ * @section sec_intro Introduction
*

+ * This is the documentation for the library interface of wimlib 1.5.3, a C
* library for creating, modifying, extracting, and mounting files in the
* Windows Imaging Format. 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 starting Getting Started
+ * @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 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 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
*
- * 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.
+ * 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.
*
- * 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.
+ * @section sec_advanced Additional information and features
*
- * First before calling any other functions, you should call
- * wimlib_global_init() to initialize the library.
*
- * To open an existing WIM, use wimlib_open_wim().
+ * @subsection subsec_mounting_wim_images Mounting WIM images
*
- * To create a new WIM that initially contains no images, use
- * wimlib_create_new_wim().
+ * See @ref G_mounting_wim_images.
*
- * 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.
+ * @subsection subsec_progress_functions Progress Messages
*
- * 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.
+ * See @ref G_progress.
*
- * To extract individual files or directories from a WIM image, rather than a
- * full image, call wimlib_extract_files().
+ * @subsection subsec_non_standalone_wims Non-standalone WIMs
*
- * To programatically make changes to a WIM image without mounting it, call
- * wimlib_update_image().
+ * See @ref G_nonstandalone_wims.
*
- * 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
- * --without-fuse 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.
