586 * LoadLibraryExA can be used to map a DLL module into the calling process's
587 * addressspace. It returns a handle that can be used with GetProcAddress to
588 * get addresses of exported entry points (functions and variables).
589 *
590 * LoadLibraryExA can also be used to map executable (.exe) modules into the
591 * address to access resources in the module. However, LoadLibrary can't be
592 * used to run an executable (.exe) module.
593 *
594 * @returns Handle to the library which was loaded.
595 * @param lpszLibFile Pointer to Unicode string giving the name of
596 * the executable image (either a Dll or an Exe) which is to
597 * be loaded.
598 *
599 * If no extention is specified the default .DLL extention is
600 * appended to the name. End the filename with an '.' if the
601 * file does not have an extention (and don't want the .DLL
602 * appended).
603 *
604 * If no path is specified, this API will use the Odin32
605 * standard search strategy to find the file. This strategy
606 * is described in the method Win32ImageBase::findDLL.
607 * This may be alterned by the LOAD_WITH_ALTERED_SEARCH_PATH
608 * flag, see below.
609 *
610 * This API likes to have backslashes (\), but will probably
611 * accept forward slashes too. Win32 SDK docs says that it
612 * should not contain forward slashes.
613 *
614 * Win32 SDK docs adds:
615 * "The name specified is the file name of the module and
616 * is not related to the name stored in the library module
617 * itself, as specified by the LIBRARY keyword in the
618 * module-definition (.def) file."
619 *
620 * @param hFile Reserved. Must be 0.
621 *
622 * @param dwFlags Flags which specifies the taken when loading the module.
623 * The value 0 makes it identical to LoadLibraryA/W.
624 *
625 * Flags:
626 *
627 * DONT_RESOLVE_DLL_REFERENCES
628 * (WinNT/2K feature): Don't load imported modules and
629 * hence don't resolve imported symbols.
630 * DllMain isn't called either. (Which is obvious since
631 * it may use one of the importe symbols.)
632 *
633 * On the other hand, if this flag is NOT set, the system
634 * load imported modules, resolves imported symbols, calls
635 * DllMain for process and thread init and term (if wished
636 * by the module).
637 *
638 *
639 * LOAD_LIBRARY_AS_DATAFILE
640 * If this flag is set, the module is mapped into the
641 * address space but is not prepared for execution. Though
642 * it's preparted for resource API. Hence, you'll use this
643 * flag when you want to load a DLL for extracting
644 * messages or resources from it.
645 *
646 * The resulting handle can be used with any Odin32 API
647 * which operates on resources.
648 * (WinNt/2k supports all resource APIs while Win9x don't
649 * support the specialized resource APIs: LoadBitmap,
650 * LoadCursor, LoadIcon, LoadImage, LoadMenu.)
651 *
652 *
653 * LOAD_WITH_ALTERED_SEARCH_PATH
654 * If this flag is set and lpszLibFile specifies a path
655 * we'll use an alternative file search strategy to find
656 * imported modules. This stratgy is simply to use the
657 * path of the module being loaded instead of the path
658 * of the executable module as the first location
659 * to search for imported modules.
660 *
661 * If this flag is clear, the standard Odin32 standard
662 * search strategy. See Win32ImageBase::findDll for
