1154  *
1155  * Try to determine the installation directory for a software package.
1156  * Typically used by GNU software packages.
1157  *
1158  * @package should be a short identifier for the package. Typically it
1159  * is the same identifier as used for
1160  * <literal>GETTEXT_PACKAGE</literal> in software configured according
1161  * to GNU standards. The function first looks in the Windows Registry
1162  * for the value <literal>&num;InstallationDirectory</literal> in the key
1163  * <literal>&num;HKLM\Software\@package</literal>, and if that value
1164  * exists and is a string, returns that.
1165  *
1166  * If @package is %NULL, or the above value isn't found in the
1167  * Registry, but @dll_name is non-%NULL, it should name a DLL loaded
1168  * into the current process. Typically that would be the name of the
1169  * DLL calling this function, looking for its installation
1170  * directory. The function then asks Windows what directory that DLL
1171  * was loaded from. If that directory's last component is "bin" or
1172  * "lib", the parent directory is returned, otherwise the directory
1173  * itself. If that DLL isn't loaded, the function proceeds as if
1174  * @dll_name was %NULL.
1175  *
1176  * If both @package and @dll_name are %NULL, the directory from where
1177  * the main executable of the process was loaded is used instead in
1178  * the same way as above.
1179  *
1180  * Returns: a string containing the installation directory for
1181  * @package. The string is in the GLib file name encoding, i.e. UTF-8
1182  * on Windows. The return value should be freed with g_free() when not

1399  * On NT-based Windows, on NTFS file systems, file names are in

1408  * entries, the short form of the filename is returned. Note that the
1409  * "short" name might in fact be longer than the Unicode name if the
1410  * Unicode name has very short pathname components containing
1411  * non-ASCII characters. If no system codepage name for the file is

1418  * failure and lack of short names.
