860 * LoadLibraryExW can be used to map a DLL module into the calling process's
861 * addressspace. It returns a handle that can be used with GetProcAddress to
862 * get addresses of exported entry points (functions and variables).
863 *
864 * LoadLibraryExW can also be used to map executable (.exe) modules into the
865 * address to access resources in the module. However, LoadLibrary can't be
866 * used to run an executable (.exe) module.
867 *
868 * @returns Handle to the library which was loaded.
869 * @param lpszLibFile Pointer to Unicode string giving the name of
870 * the executable image (either a Dll or an Exe) which is to
871 * be loaded.
872 *
873 * If no extention is specified the default .DLL extention is
874 * appended to the name. End the filename with an '.' if the
875 * file does not have an extention (and don't want the .DLL
876 * appended).
877 *
878 * If no path is specified, this API will use the Odin32
879 * standard search strategy to find the file. This strategy
880 * is described in the method Win32ImageBase::findDLL.
881 * This may be alterned by the LOAD_WITH_ALTERED_SEARCH_PATH
882 * flag, see below.
883 *
884 * This API likes to have backslashes (\), but will probably
885 * accept forward slashes too. Win32 SDK docs says that it
886 * should not contain forward slashes.
887 *
888 * Win32 SDK docs adds:
889 * "The name specified is the file name of the module and
890 * is not related to the name stored in the library module
891 * itself, as specified by the LIBRARY keyword in the
892 * module-definition (.def) file."
893 *
894 * @param hFile Reserved. Must be 0.
895 *
896 * @param dwFlags Flags which specifies the taken when loading the module.
897 * The value 0 makes it identical to LoadLibraryA/W.
898 *
899 * Flags:
900 *
901 * DONT_RESOLVE_DLL_REFERENCES
902 * (WinNT/2K feature): Don't load imported modules and
903 * hence don't resolve imported symbols.
904 * DllMain isn't called either. (Which is obvious since
905 * it may use one of the importe symbols.)
906 *
907 * On the other hand, if this flag is NOT set, the system
908 * load imported modules, resolves imported symbols, calls
909 * DllMain for process and thread init and term (if wished
910 * by the module).
911 *
912 * LOAD_LIBRARY_AS_DATAFILE
913 * If this flag is set, the module is mapped into the
914 * address space but is not prepared for execution. Though
915 * it's preparted for resource API. Hence, you'll use this
