582/**
583 * LoadLibraryExA can be used to map a DLL module into the calling process's
584 * addressspace. It returns a handle that can be used with GetProcAddress to
585 * get addresses of exported entry points (functions and variables).
586 *
587 * LoadLibraryExA can also be used to map executable (.exe) modules into the
588 * address to access resources in the module. However, LoadLibrary can't be
589 * used to run an executable (.exe) module.
590 *
591 * @returns Handle to the library which was loaded.
592 * @param lpszLibFile Pointer to Unicode string giving the name of
593 * the executable image (either a Dll or an Exe) which is to
594 * be loaded.
595 *
596 * If no extention is specified the default .DLL extention is
597 * appended to the name. End the filename with an '.' if the
598 * file does not have an extention (and don't want the .DLL
599 * appended).
600 *
601 * If no path is specified, this API will use the Odin32
602 * standard search strategy to find the file. This strategy
603 * is described in the method Win32ImageBase::findDLL.
604 * This may be alterned by the LOAD_WITH_ALTERED_SEARCH_PATH
605 * flag, see below.
606 *
607 * This API likes to have backslashes (\), but will probably
608 * accept forward slashes too. Win32 SDK docs says that it
609 * should not contain forward slashes.
610 *
611 * Win32 SDK docs adds:
612 * "The name specified is the file name of the module and
613 * is not related to the name stored in the library module
614 * itself, as specified by the LIBRARY keyword in the
615 * module-definition (.def) file."
616 *
617 * @param hFile Reserved. Must be 0.
618 *
619 * @param dwFlags Flags which specifies the taken when loading the module.
620 * The value 0 makes it identical to LoadLibraryA/W.
621 *
622 * Flags:
623 *
624 * DONT_RESOLVE_DLL_REFERENCES
625 * (WinNT/2K feature): Don't load imported modules and
626 * hence don't resolve imported symbols.
627 * DllMain isn't called either. (Which is obvious since
628 * it may use one of the importe symbols.)
629 *
630 * On the other hand, if this flag is NOT set, the system
631 * load imported modules, resolves imported symbols, calls
632 * DllMain for process and thread init and term (if wished
633 * by the module).
634 *
635 * partially implemented yet - imports are resolved it seems.
636 *
637 * LOAD_LIBRARY_AS_DATAFILE
638 * If this flag is set, the module is mapped into the
639 * address space but is not prepared for execution. Though
640 * it's preparted for resource API. Hence, you'll use this
641 * flag when you want to load a DLL for extracting
642 * messages or resources from it.
643 *
644 * The resulting handle can be used with any Odin32 API
645 * which operates on resources.
646 * (WinNt/2k supports all resource APIs while Win9x don't
647 * support the specialized resource APIs: LoadBitmap,
648 * LoadCursor, LoadIcon, LoadImage, LoadMenu.)
649 *
650 * not implemented yet.
651 *
652 * LOAD_WITH_ALTERED_SEARCH_PATH
653 * If this flag is set and lpszLibFile specifies a path
654 * we'll use an alternative file search strategy to find
655 * imported modules. This stratgy is simply to use the
656 * path of the module being loaded instead of the path
657 * of the executable module as the first location
658 * to search for imported modules.
659 *
660 * If this flag is clear, the standard Odin32 standard
661 * search strategy. See Win32ImageBase::findDll for
662 * further information.
663 *
664 * not implemented yet.
