571 * LoadLibraryExA can be used to map a DLL module into the calling process's
572 * addressspace. It returns a handle that can be used with GetProcAddress to
573 * get addresses of exported entry points (functions and variables).
574 *
575 * LoadLibraryExA can also be used to map executable (.exe) modules into the
576 * address to access resources in the module. However, LoadLibrary can't be
577 * used to run an executable (.exe) module.
578 *
579 * @returns Handle to the library which was loaded.
580 * @param lpszLibFile Pointer to Unicode string giving the name of
581 * the executable image (either a Dll or an Exe) which is to
582 * be loaded.
583 *
584 * If no extention is specified the default .DLL extention is
585 * appended to the name. End the filename with an '.' if the
586 * file does not have an extention (and don't want the .DLL
587 * appended).
588 *
589 * If no path is specified, this API will use the Odin32
590 * standard search strategy to find the file. This strategy
591 * is described in the method Win32ImageBase::findDLL.
592 * This may be alterned by the LOAD_WITH_ALTERED_SEARCH_PATH
593 * flag, see below.
594 *
595 * This API likes to have backslashes (\), but will probably
596 * accept forward slashes too. Win32 SDK docs says that it
597 * should not contain forward slashes.
598 *
599 * Win32 SDK docs adds:
600 * "The name specified is the file name of the module and
601 * is not related to the name stored in the library module
602 * itself, as specified by the LIBRARY keyword in the
603 * module-definition (.def) file."
604 *
605 * @param hFile Reserved. Must be 0.
606 *
607 * @param dwFlags Flags which specifies the taken when loading the module.
608 * The value 0 makes it identical to LoadLibraryA/W.
609 *
610 * Flags:
611 *
612 * DONT_RESOLVE_DLL_REFERENCES
613 * (WinNT/2K feature): Don't load imported modules and
614 * hence don't resolve imported symbols.
615 * DllMain isn't called either. (Which is obvious since
616 * it may use one of the importe symbols.)
617 *
618 * On the other hand, if this flag is NOT set, the system
619 * load imported modules, resolves imported symbols, calls
620 * DllMain for process and thread init and term (if wished
621 * by the module).
622 *
623 * partially implemented yet - imports are resolved it seems.
624 *
625 * LOAD_LIBRARY_AS_DATAFILE
626 * If this flag is set, the module is mapped into the
627 * address space but is not prepared for execution. Though
628 * it's preparted for resource API. Hence, you'll use this
629 * flag when you want to load a DLL for extracting
630 * messages or resources from it.
631 *
632 * The resulting handle can be used with any Odin32 API
633 * which operates on resources.
634 * (WinNt/2k supports all resource APIs while Win9x don't
635 * support the specialized resource APIs: LoadBitmap,
636 * LoadCursor, LoadIcon, LoadImage, LoadMenu.)
637 *
638 * not implemented yet.
639 *
640 * LOAD_WITH_ALTERED_SEARCH_PATH
641 * If this flag is set and lpszLibFile specifies a path
642 * we'll use an alternative file search strategy to find
643 * imported modules. This stratgy is simply to use the
644 * path of the module being loaded instead of the path
645 * of the executable module as the first location
646 * to search for imported modules.
647 *
648 * If this flag is clear, the standard Odin32 standard
649 * search strategy. See Win32ImageBase::findDll for
650 * further information.
651 *
652 * not implemented yet.
