574 * LoadLibraryExA can be used to map a DLL module into the calling process's
575 * addressspace. It returns a handle that can be used with GetProcAddress to
576 * get addresses of exported entry points (functions and variables).
577 *
578 * LoadLibraryExA can also be used to map executable (.exe) modules into the
579 * address to access resources in the module. However, LoadLibrary can't be
580 * used to run an executable (.exe) module.
581 *
582 * @returns Handle to the library which was loaded.
583 * @param lpszLibFile Pointer to Unicode string giving the name of
584 * the executable image (either a Dll or an Exe) which is to
585 * be loaded.
586 *
587 * If no extention is specified the default .DLL extention is
588 * appended to the name. End the filename with an '.' if the
589 * file does not have an extention (and don't want the .DLL
590 * appended).
591 *
592 * If no path is specified, this API will use the Odin32
593 * standard search strategy to find the file. This strategy
594 * is described in the method Win32ImageBase::findDLL.
595 * This may be alterned by the LOAD_WITH_ALTERED_SEARCH_PATH
596 * flag, see below.
597 *
598 * This API likes to have backslashes (\), but will probably
599 * accept forward slashes too. Win32 SDK docs says that it
600 * should not contain forward slashes.
601 *
602 * Win32 SDK docs adds:
603 * "The name specified is the file name of the module and
604 * is not related to the name stored in the library module
605 * itself, as specified by the LIBRARY keyword in the
606 * module-definition (.def) file."
607 *
608 * @param hFile Reserved. Must be 0.
609 *
610 * @param dwFlags Flags which specifies the taken when loading the module.
611 * The value 0 makes it identical to LoadLibraryA/W.
612 *
613 * Flags:
614 *
615 * DONT_RESOLVE_DLL_REFERENCES
616 * (WinNT/2K feature): Don't load imported modules and
617 * hence don't resolve imported symbols.
618 * DllMain isn't called either. (Which is obvious since
619 * it may use one of the importe symbols.)
620 *
621 * On the other hand, if this flag is NOT set, the system
622 * load imported modules, resolves imported symbols, calls
623 * DllMain for process and thread init and term (if wished
624 * by the module).
625 *
626 *
627 * LOAD_LIBRARY_AS_DATAFILE
628 * If this flag is set, the module is mapped into the
629 * address space but is not prepared for execution. Though
630 * it's preparted for resource API. Hence, you'll use this
631 * flag when you want to load a DLL for extracting
632 * messages or resources from it.
633 *
634 * The resulting handle can be used with any Odin32 API
635 * which operates on resources.
636 * (WinNt/2k supports all resource APIs while Win9x don't
637 * support the specialized resource APIs: LoadBitmap,
638 * LoadCursor, LoadIcon, LoadImage, LoadMenu.)
639 *
640 *
641 * LOAD_WITH_ALTERED_SEARCH_PATH
642 * If this flag is set and lpszLibFile specifies a path
643 * we'll use an alternative file search strategy to find
644 * imported modules. This stratgy is simply to use the
645 * path of the module being loaded instead of the path
646 * of the executable module as the first location
647 * to search for imported modules.
648 *
649 * If this flag is clear, the standard Odin32 standard
650 * search strategy. See Win32ImageBase::findDll for
