* This file is part of wimlib, a library for working with WIM files.
*
*
* \section intro Introduction
*
- * This is the documentation for the library interface of wimlib 1.2.5. If you
- * have installed wimlib and want to know how to use the @c imagex program,
- * please see the man pages instead.
+ * This is the documentation for the library interface of wimlib 1.3.2. If you
+ * have installed wimlib and want to know how to use the @b wimlib-imagex
+ * program, please see the man pages instead. Also: the actual project page
+ * where you can download the source code for the library is at <a
+ * href="https://sourceforge.net/projects/wimlib">https://sourceforge.net/projects/wimlib</a>.
*
* wimlib is a C library to read, write, and mount archive files in the Windows
- * Imaging Format (WIM files). These files are normally created using the @c
- * imagex.exe utility on Windows, but this library provides a free
- * implementetion of @c imagex for UNIX-based systems and an API to allow other
- * programs to read, write, and mount WIM files. wimlib is comparable to
- * Microsoft's WIMGAPI, but was designed independently and is not a clone of it.
+ * Imaging Format (WIM files). These files are normally created using the
+ * ImageX (@a imagex.exe) utility on Windows, but this library provides a free
+ * implementation of ImageX for UNIX-based systems (and, since v1.3.0, for
+ * Windows systems) and an API to allow other programs to read, write, and mount
+ * WIM files. wimlib is comparable to Microsoft's WIMGAPI, but was designed
+ * independently and is not a clone of it.
*
* \section format WIM files
*
* Configuration Data. In addition, a Windows installation can be captured (or
* backed up) into a WIM file, and then re-applied later.
*
+ * wimlib v1.3.0 and later also supports NTFS capture and apply in the native
+ * Windows build, which works slightly differently and relies on native Win32
+ * API calls rather than libntfs-3g.
+ *
* \section winpe Windows PE
*
* A major use for this library is to create customized images of Windows PE, the
* message being printed.
*
* wimlib is thread-safe as long as different ::WIMStruct's are used, except for
- * the fact that wimlib_set_print_errors() and wimlib_set_memory_allocator()
- * both apply globally, and you also must call wimlib_global_init() in the main
- * thread to avoid any race conditions with one-time allocations of memory.
+ * the following exceptions:
+ * - wimlib_set_print_errors() and wimlib_set_memory_allocator() both apply globally.
+ * - You also must call wimlib_global_init() in the main thread to avoid any
+ * race conditions with one-time allocations of memory.
+ * - 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.
*
* To open an existing WIM, use wimlib_open_wim().
*
* the WIM operation(s) to report on the progress of the operation (for example,
* how many bytes have been written so far).
*
- * \section imagex imagex
+ * \section imagex wimlib-imagex
*
- * wimlib comes with a command-line interface, the @b imagex program. It is
- * documented with man pages. See its source code (@c programs/imagex.c in
- * wimlib's source tree) for an example of how to use wimlib in your program.
+ * wimlib comes with a command-line interface, the @b wimlib-imagex program. It
+ * is documented with man pages. This program was originally just called @b
+ * imagex, but has been changed to @b wimlib-imagex to avoid confusion with
+ * Microsoft's @a imagex.exe (which would otherwise have exactly the same
+ * filename on Windows).
*
* \section mkwinpeimg mkwinpeimg
*
* wimlib also comes with the <b>mkwinpeimg</b> script, which is documented in a
* man page.
+ *
+ * \section encodings Locales and character encodings
+ *
+ * To support Windows as well as UNIX, 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, 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 Limitations
*
* While wimlib supports the main features of WIM files, wimlib currently has
* the following limitations:
- * - wimlib cannot be used on MS-Windows.
* - There is no way to add, remove, modify, or extract specific files in a WIM
* without mounting it, other than by adding, removing, or extracting an
* entire image. The FUSE mount feature should be used for this purpose.
* - Currently, Microsoft's @a image.exe can create slightly smaller WIM files
- * than wimlib when using maximum (LZX) compression because it knows how to
- * split up LZX compressed blocks, which is not yet implemented in wimlib.
+ * than wimlib (~2% or 3% smaller) when using maximum (LZX) compression.
* - wimlib is experimental and likely contains bugs; use Microsoft's @a
* imagex.exe if you want to make sure your WIM files are made "correctly".
* - The old WIM format from Vista pre-releases is not supported.
* script for a similar purpose, however. With regards to adding drivers to
* Windows PE, you have the option of putting them anywhere in the Windows PE
* image, then loading them after boot using @b drvload.exe.
+ * - Although wimlib 1.3.0 and later can be used on Windows as well as UNIX, the
+ * Windows build has some limitations compared to the UNIX build.
+ * (The differences are documented better in the man pages for
+ * @b wimlib-imagex than here.)
