753 * hence don't resolve imported symbols.
754 * DllMain isn't called either. (Which is obvious since
755 * it may use one of the importe symbols.)
756 *
757 * On the other hand, if this flag is NOT set, the system
758 * load imported modules, resolves imported symbols, calls
759 * DllMain for process and thread init and term (if wished
760 * by the module).
761 *
762 *
763 * LOAD_LIBRARY_AS_DATAFILE
764 * If this flag is set, the module is mapped into the
765 * address space but is not prepared for execution. Though
766 * it's preparted for resource API. Hence, you'll use this
767 * flag when you want to load a DLL for extracting
768 * messages or resources from it.
769 *
770 * The resulting handle can be used with any Odin32 API
771 * which operates on resources.
772 * (WinNt/2k supports all resource APIs while Win9x don't
773 * support the specialized resource APIs: LoadBitmap,
774 * LoadCursor, LoadIcon, LoadImage, LoadMenu.)
775 *
776 *
777 * LOAD_WITH_ALTERED_SEARCH_PATH
778 * If this flag is set and lpszLibFile specifies a path
779 * we'll use an alternative file search strategy to find
780 * imported modules. This stratgy is simply to use the
781 * path of the module being loaded instead of the path
782 * of the executable module as the first location
783 * to search for imported modules.
784 *

1095/**
1096 * LoadLibraryExW can be used to map a DLL module into the calling process's
1097 * addressspace. It returns a handle that can be used with GetProcAddress to
1098 * get addresses of exported entry points (functions and variables).
1099 *
1100 * LoadLibraryExW can also be used to map executable (.exe) modules into the
1101 * address to access resources in the module. However, LoadLibrary can't be
1102 * used to run an executable (.exe) module.
1103 *
1104 * @returns Handle to the library which was loaded.
1105 * @param lpszLibFile Pointer to Unicode string giving the name of
1106 * the executable image (either a Dll or an Exe) which is to
1107 * be loaded.
1108 *
1109 * If no extention is specified the default .DLL extention is
1110 * appended to the name. End the filename with an '.' if the
1111 * file does not have an extention (and don't want the .DLL
1112 * appended).
1113 *
1114 * If no path is specified, this API will use the Odin32
1115 * standard search strategy to find the file. This strategy
1116 * is described in the method Win32ImageBase::findDLL.
1117 * This may be alterned by the LOAD_WITH_ALTERED_SEARCH_PATH
1118 * flag, see below.
1119 *
1120 * This API likes to have backslashes (\), but will probably
1121 * accept forward slashes too. Win32 SDK docs says that it
1122 * should not contain forward slashes.
1123 *
1124 * Win32 SDK docs adds:
1125 * "The name specified is the file name of the module and
1126 * is not related to the name stored in the library module
1127 * itself, as specified by the LIBRARY keyword in the
1128 * module-definition (.def) file."
1129 *
1130 * @param hFile Reserved. Must be 0.
1131 *
1132 * @param dwFlags Flags which specifies the taken when loading the module.
1133 * The value 0 makes it identical to LoadLibraryA/W.
1134 *
1135 * Flags:
1136 *
1137 * DONT_RESOLVE_DLL_REFERENCES
1138 * (WinNT/2K feature): Don't load imported modules and
1139 * hence don't resolve imported symbols.
1140 * DllMain isn't called either. (Which is obvious since
1141 * it may use one of the importe symbols.)
1142 *
1143 * On the other hand, if this flag is NOT set, the system
1144 * load imported modules, resolves imported symbols, calls
1145 * DllMain for process and thread init and term (if wished
1146 * by the module).
1147 *
1148 * LOAD_LIBRARY_AS_DATAFILE
1149 * If this flag is set, the module is mapped into the
1150 * address space but is not prepared for execution. Though
1151 * it's preparted for resource API. Hence, you'll use this
1152 * flag when you want to load a DLL for extracting
1153 * messages or resources from it.
1154 *
1155 * The resulting handle can be used with any Odin32 API
1156 * which operates on resources.
1157 * (WinNt/2k supports all resource APIs while Win9x don't
1158 * support the specialized resource APIs: LoadBitmap,
1159 * LoadCursor, LoadIcon, LoadImage, LoadMenu.)
1160 *
1161 * LOAD_WITH_ALTERED_SEARCH_PATH
1162 * If this flag is set and lpszLibFile specifies a path
1163 * we'll use an alternative file search strategy to find
1164 * imported modules. This stratgy is simply to use the
1165 * path of the module being loaded instead of the path
1166 * of the executable module as the first location
1167 * to search for imported modules.
1168 *
1169 * If this flag is clear, the standard Odin32 standard
1170 * search strategy. See Win32ImageBase::findDll for
1171 * further information.
1172 *
1173 * @sketch Convert Unicode name to ascii.
1174 * Call LoadLibraryExA.
1175 * Free ascii string.
