220 * g_win32_get_package_installation_directory_of_module:

223 * This function tries to determine the installation directory of a
224 * software package based on the location of a DLL of the software
225 * package.
227 * @hmodule should be the handle of a loaded DLL or %NULL. The
228 * function looks up the directory that DLL was loaded from. If
229 * @hmodule is NULL, the directory the main executable of the current
230 * process is looked up. If that directory's last component is "bin"
231 * or "lib", its parent directory is returned, otherwise the directory
232 * itself.
234 * It thus makes sense to pass only the handle to a "public" DLL of a
235 * software package to this function, as such DLLs typically are known
236 * to be installed in a "bin" or occasionally "lib" subfolder of the
237 * installation folder. DLLs that are of the dynamically loaded module
238 * or plugin variety are often located in more private locations
239 * deeper down in the tree, from which it is impossible for GLib to
240 * deduce the root of the package installation.
242 * The typical use case for this function is to have a DllMain() that
243 * saves the handle for the DLL. Then when code in the DLL needs to
244 * construct names of files in the installation tree it calls this
245 * function passing the DLL handle.
247 * Returns: a string containing the guessed installation directory for
248 * the software package @hmodule is from. The string is in the GLib
249 * file name encoding, i.e. UTF-8. The return value should be freed
250 * with g_free() when not needed any longer. If the function fails
251 * %NULL is returned.

369 * The use of @package is deprecated. You should always pass %NULL. A
370 * warning is printed if non-NULL is passed as @package.
372 * The original intended use of @package was for a short identifier of
373 * the package, typically the same identifier as used for
374 * `GETTEXT_PACKAGE` in software configured using GNU
375 * autotools. The function first looks in the Windows Registry for the
376 * value `#InstallationDirectory` in the key
377 * `#HKLM\Software\@package`, and if that value
378 * exists and is a string, returns that.
380 * It is strongly recommended that packagers of GLib-using libraries
381 * for Windows do not store installation paths in the Registry to be
382 * used by this function as that interfers with having several
383 * parallel installations of the library. Enabling multiple
384 * installations of different versions of some GLib-using library, or
385 * GLib itself, is desirable for various reasons.
387 * For this reason it is recommeded to always pass %NULL as
388 * @package to this function, to avoid the temptation to use the
389 * Registry. In version 2.20 of GLib the @package parameter
390 * will be ignored and this function won't look in the Registry at all.
392 * If @package is %NULL, or the above value isn't found in the
393 * Registry, but @dll_name is non-%NULL, it should name a DLL loaded
394 * into the current process. Typically that would be the name of the
395 * DLL calling this function, looking for its installation
396 * directory. The function then asks Windows what directory that DLL
397 * was loaded from. If that directory's last component is "bin" or
398 * "lib", the parent directory is returned, otherwise the directory
399 * itself. If that DLL isn't loaded, the function proceeds as if
400 * @dll_name was %NULL.
402 * If both @package and @dll_name are %NULL, the directory from where
403 * the main executable of the process was loaded is used instead in
404 * the same way as above.
406 * Returns: a string containing the installation directory for
407 * @package. The string is in the GLib file name encoding,
408 * i.e. UTF-8. The return value should be freed with g_free() when not
409 * needed any longer. If the function fails %NULL is returned.

671 * Greek or Cyrillic characters on Western European or US Windows
672 * installations, or various less common CJK characters on CJK Windows
673 * installations.)
675 * In such a case, and if the filename refers to an existing file, and
676 * the file system stores alternate short (8.3) names for directory
677 * entries, the short form of the filename is returned. Note that the
678 * "short" name might in fact be longer than the Unicode name if the
679 * Unicode name has very short pathname components containing
680 * non-ASCII characters. If no system codepage name for the file is
681 * possible, %NULL is returned.
683 * The return value is dynamically allocated and should be freed with
684 * g_free() when no longer needed.
686 * Returns: The converted filename, or %NULL on conversion
687 * failure and lack of short names.

719 * g_win32_get_command_line:
721 * Gets the command line arguments, on Windows, in the GLib filename
722 * encoding (ie: UTF-8).
724 * Normally, on Windows, the command line arguments are passed to main()
725 * in the system codepage encoding. This prevents passing filenames as
726 * arguments if the filenames contain characters that fall outside of
727 * this codepage. If such filenames are passed, then substitutions
728 * will occur (such as replacing some characters with '?').
730 * GLib's policy of using UTF-8 as a filename encoding on Windows was
731 * designed to localise the pain of dealing with filenames outside of
732 * the system codepage to one area: dealing with commandline arguments
733 * in main().
735 * As such, most GLib programs should ignore the value of argv passed to
736 * their main() function and call g_win32_get_command_line() instead.
737 * This will get the "full Unicode" commandline arguments using
738 * GetCommandLineW() and convert it to the GLib filename encoding (which
739 * is UTF-8 on Windows).
741 * The strings returned by this function are suitable for use with
742 * functions such as g_open() and g_file_new_for_commandline_arg() but
743 * are not suitable for use with g_option_context_parse(), which assumes
744 * that its input will be in the system codepage. The return value is
745 * suitable for use with g_option_context_parse_strv(), however, which
746 * is a better match anyway because it won't leak memory.
748 * Unlike argv, the returned value is a normal strv and can (and should)
749 * be freed with g_strfreev() when no longer needed.
751 * Returns: (transfer full): the commandline arguments in the GLib
752 * filename encoding (ie: UTF-8)
754 * Since: 2.40
