 *
 *                  DONT_RESOLVE_DLL_REFERENCES
 *                      (WinNT/2K feature): Don't load imported modules and
 *                      hence don't resolve imported symbols.
 *                      DllMain isn't called either. (Which is obvious since
 *                      it may use one of the importe symbols.)
 *
 *                      On the other hand, if this flag is NOT set, the system
 *                      load imported modules, resolves imported symbols, calls
 *                      DllMain for process and thread init and term (if wished
 *                      by the module).
 *
 *
 *                  LOAD_LIBRARY_AS_DATAFILE
 *                      If this flag is set, the module is mapped into the
 *                      address space but is not prepared for execution. Though
 *                      it's preparted for resource API. Hence, you'll use this
 *                      flag when you want to load a DLL for extracting
 *                      messages or resources from it.
 *
 *                      The resulting handle can be used with any Odin32 API
 *                      which operates on resources.
 *                      (WinNt/2k supports all resource APIs while Win9x don't
 *                      support the specialized resource APIs: LoadBitmap,
 *                      LoadCursor, LoadIcon, LoadImage, LoadMenu.)
 *
 *
 *                  LOAD_WITH_ALTERED_SEARCH_PATH
 *                      If this flag is set and lpszLibFile specifies a path
 *                      we'll use an alternative file search strategy to find
 *                      imported modules. This stratgy is simply to use the
 *                      path of the module being loaded instead of the path
 *                      of the executable module as the first location
 *                      to search for imported modules.
 *
 *                      If this flag is clear, the standard Odin32 standard
 *                      search strategy. See Win32ImageBase::findDll for

/**
 * LoadLibraryExW can be used to map a DLL module into the calling process's
 * addressspace. It returns a handle that can be used with GetProcAddress to
 * get addresses of exported entry points (functions and variables).
 *
 * LoadLibraryExW can also be used to map executable (.exe) modules into the
 * address to access resources in the module. However, LoadLibrary can't be
 * used to run an executable (.exe) module.
 *
 * @returns   Handle to the library which was loaded.
 * @param     lpszLibFile   Pointer to Unicode string giving the name of
 *                  the executable image (either a Dll or an Exe) which is to
 *                  be loaded.
 *
 *                  If no extention is specified the default .DLL extention is
 *                  appended to the name. End the filename with an '.' if the
 *                  file does not have an extention (and don't want the .DLL
 *                  appended).
 *
 *                  If no path is specified, this API will use the Odin32
 *                  standard search strategy to find the file. This strategy
 *                  is described in the method Win32ImageBase::findDLL.
 *                  This may be alterned by the LOAD_WITH_ALTERED_SEARCH_PATH
 *                  flag, see below.
 *
 *                  This API likes to have backslashes (\), but will probably
 *                  accept forward slashes too. Win32 SDK docs says that it
 *                  should not contain forward slashes.
 *
 *                  Win32 SDK docs adds:
 *                      "The name specified is the file name of the module and
 *                       is not related to the name stored in the library module
 *                       itself, as specified by the LIBRARY keyword in the
 *                       module-definition (.def) file."
 *
 * @param     hFile     Reserved. Must be 0.
 *
 * @param     dwFlags   Flags which specifies the taken when loading the module.
 *                  The value 0 makes it identical to LoadLibraryA/W.
 *
 *                  Flags:
 *
 *                  DONT_RESOLVE_DLL_REFERENCES
 *                      (WinNT/2K feature): Don't load imported modules and
 *                      hence don't resolve imported symbols.
 *                      DllMain isn't called either. (Which is obvious since
 *                      it may use one of the importe symbols.)
 *
 *                      On the other hand, if this flag is NOT set, the system
 *                      load imported modules, resolves imported symbols, calls
 *                      DllMain for process and thread init and term (if wished
 *                      by the module).
 *
 *                  LOAD_LIBRARY_AS_DATAFILE
 *                      If this flag is set, the module is mapped into the
 *                      address space but is not prepared for execution. Though
 *                      it's preparted for resource API. Hence, you'll use this
 *                      flag when you want to load a DLL for extracting
 *                      messages or resources from it.
 *
 *                      The resulting handle can be used with any Odin32 API
 *                      which operates on resources.
 *                      (WinNt/2k supports all resource APIs while Win9x don't
 *                      support the specialized resource APIs: LoadBitmap,
 *                      LoadCursor, LoadIcon, LoadImage, LoadMenu.)
 *
 *                  LOAD_WITH_ALTERED_SEARCH_PATH
 *                      If this flag is set and lpszLibFile specifies a path
 *                      we'll use an alternative file search strategy to find
 *                      imported modules. This stratgy is simply to use the
 *                      path of the module being loaded instead of the path
 *                      of the executable module as the first location
 *                      to search for imported modules.
 *
 *                      If this flag is clear, the standard Odin32 standard
 *                      search strategy. See Win32ImageBase::findDll for
 *                      further information.
