250 | =head1 NAME |
251 | |
252 | Win32 - Interfaces to some Win32 API Functions |
253 | |
254 | =head1 DESCRIPTION |
255 | |
82adc83d |
256 | The Win32 module contains functions to access Win32 APIs. |
b4ad57f4 |
257 | |
258 | =head2 Alphabetical Listing of Win32 Functions |
259 | |
82adc83d |
260 | It is recommended to C<use Win32;> before any of these functions; |
261 | however, for backwards compatibility, those marked as [CORE] will |
262 | automatically do this for you. |
263 | |
34f7f30d |
264 | In the function descriptions below the term I<Unicode string> is used |
265 | to indicate that the string may contain characters outside the system |
266 | codepage. The caveat I<If supported by the core Perl version> |
267 | generally means Perl 5.8.9 and later, though some Unicode pathname |
268 | functionality may work on earlier versions. |
269 | |
b4ad57f4 |
270 | =over |
271 | |
272 | =item Win32::AbortSystemShutdown(MACHINE) |
273 | |
82adc83d |
274 | Aborts a system shutdown (started by the |
b4ad57f4 |
275 | InitiateSystemShutdown function) on the specified MACHINE. |
276 | |
277 | =item Win32::BuildNumber() |
278 | |
279 | [CORE] Returns the ActivePerl build number. This function is |
280 | only available in the ActivePerl binary distribution. |
281 | |
282 | =item Win32::CopyFile(FROM, TO, OVERWRITE) |
283 | |
284 | [CORE] The Win32::CopyFile() function copies an existing file to a new |
285 | file. All file information like creation time and file attributes will |
286 | be copied to the new file. However it will B<not> copy the security |
287 | information. If the destination file already exists it will only be |
288 | overwritten when the OVERWRITE parameter is true. But even this will |
289 | not overwrite a read-only file; you have to unlink() it first |
290 | yourself. |
291 | |
34f7f30d |
292 | =item Win32::CreateDirectory(DIRECTORY) |
293 | |
294 | Creates the DIRECTORY and returns a true value on success. Check $^E |
295 | on failure for extended error information. |
296 | |
297 | DIRECTORY may contain Unicode characters outside the system codepage. |
298 | Once the directory has been created you can use |
299 | Win32::GetANSIPathName() to get a name that can be passed to system |
300 | calls and external programs. |
301 | |
302 | =item Win32::CreateFile(FILE) |
303 | |
304 | Creates the FILE and returns a true value on success. Check $^E on |
305 | failure for extended error information. |
306 | |
307 | FILE may contain Unicode characters outside the system codepage. Once |
308 | the file has been created you can use Win32::GetANSIPathName() to get |
309 | a name that can be passed to system calls and external programs. |
310 | |
b4ad57f4 |
311 | =item Win32::DomainName() |
312 | |
313 | [CORE] Returns the name of the Microsoft Network domain that the |
314 | owner of the current perl process is logged into. This function does |
315 | B<not> work on Windows 9x. |
316 | |
317 | =item Win32::ExpandEnvironmentStrings(STRING) |
318 | |
82adc83d |
319 | Takes STRING and replaces all referenced environment variable |
b4ad57f4 |
320 | names with their defined values. References to environment variables |
321 | take the form C<%VariableName%>. Case is ignored when looking up the |
322 | VariableName in the environment. If the variable is not found then the |
323 | original C<%VariableName%> text is retained. Has the same effect |
324 | as the following: |
325 | |
326 | $string =~ s/%([^%]*)%/$ENV{$1} || "%$1%"/eg |
327 | |
34f7f30d |
328 | However, this function may return a Unicode string if the environment |
329 | variable being expanded hasn't been assigned to via %ENV. Access |
330 | to %ENV is currently always using byte semantics. |
331 | |
b4ad57f4 |
332 | =item Win32::FormatMessage(ERRORCODE) |
333 | |
334 | [CORE] Converts the supplied Win32 error number (e.g. returned by |
335 | Win32::GetLastError()) to a descriptive string. Analogous to the |
336 | perror() standard-C library function. Note that C<$^E> used |
337 | in a string context has much the same effect. |
338 | |
339 | C:\> perl -e "$^E = 26; print $^E;" |
340 | The specified disk or diskette cannot be accessed |
341 | |
342 | =item Win32::FsType() |
343 | |
344 | [CORE] Returns the name of the filesystem of the currently active |
345 | drive (like 'FAT' or 'NTFS'). In list context it returns three values: |
346 | (FSTYPE, FLAGS, MAXCOMPLEN). FSTYPE is the filesystem type as |
347 | before. FLAGS is a combination of values of the following table: |
348 | |
349 | 0x00000001 supports case-sensitive filenames |
350 | 0x00000002 preserves the case of filenames |
351 | 0x00000004 supports Unicode in filenames |
352 | 0x00000008 preserves and enforces ACLs |
353 | 0x00000010 supports file-based compression |
354 | 0x00000020 supports disk quotas |
355 | 0x00000040 supports sparse files |
356 | 0x00000080 supports reparse points |
357 | 0x00000100 supports remote storage |
358 | 0x00008000 is a compressed volume (e.g. DoubleSpace) |
359 | 0x00010000 supports object identifiers |
360 | 0x00020000 supports the Encrypted File System (EFS) |
361 | |
362 | MAXCOMPLEN is the maximum length of a filename component (the part |
363 | between two backslashes) on this file system. |
364 | |
365 | =item Win32::FreeLibrary(HANDLE) |
366 | |
82adc83d |
367 | Unloads a previously loaded dynamic-link library. The HANDLE is |
b4ad57f4 |
368 | no longer valid after this call. See L<LoadLibrary|Win32::LoadLibrary(LIBNAME)> |
369 | for information on dynamically loading a library. |
370 | |
34f7f30d |
371 | =item Win32::GetANSIPathName(FILENAME) |
372 | |
373 | Returns an ANSI version of FILENAME. This may be the short name |
374 | if the long name cannot be represented in the system codepage. |
375 | |
376 | While not currently implemented, it is possible that in the future |
377 | this function will convert only parts of the path to FILENAME to a |
378 | short form. |
379 | |
380 | If FILENAME doesn't exist on the filesystem, or if the filesystem |
381 | doesn't support short ANSI filenames, then this function will |
382 | translate the Unicode name into the system codepage using replacement |
383 | characters. |
384 | |
b4ad57f4 |
385 | =item Win32::GetArchName() |
386 | |
82adc83d |
387 | Use of this function is deprecated. It is equivalent with |
b4ad57f4 |
388 | $ENV{PROCESSOR_ARCHITECTURE}. This might not work on Win9X. |
389 | |
390 | =item Win32::GetChipName() |
391 | |
82adc83d |
392 | Returns the processor type: 386, 486 or 586 for Intel processors, |
b4ad57f4 |
393 | 21064 for the Alpha chip. |
394 | |
395 | =item Win32::GetCwd() |
396 | |
397 | [CORE] Returns the current active drive and directory. This function |
398 | does not return a UNC path, since the functionality required for such |
399 | a feature is not available under Windows 95. |
400 | |
34f7f30d |
401 | If supported by the core Perl version, this function will return an |
402 | ANSI path name for the current directory if the long pathname cannot |
403 | be represented in the system codepage. |
404 | |
405 | =item Win32::GetCurrentThreadId() |
406 | |
407 | Returns the thread identifier of the calling thread. Until the thread |
408 | terminates, the thread identifier uniquely identifies the thread |
409 | throughout the system. |
410 | |
411 | Note: the current process identifier is available via the predefined |
412 | $$ variable. |
413 | |
e364e11c |
414 | =item Win32::GetFileVersion(FILENAME) |
415 | |
82adc83d |
416 | Returns the file version number from the VERSIONINFO resource of |
e364e11c |
417 | the executable file or DLL. This is a tuple of four 16 bit numbers. |
418 | In list context these four numbers will be returned. In scalar context |
419 | they are concatenated into a string, separated by dots. |
420 | |
b4ad57f4 |
421 | =item Win32::GetFolderPath(FOLDER [, CREATE]) |
422 | |
82adc83d |
423 | Returns the full pathname of one of the Windows special folders. |
b4ad57f4 |
424 | The folder will be created if it doesn't exist and the optional CREATE |
425 | argument is true. The following FOLDER constants are defined by the |
426 | Win32 module, but only exported on demand: |

34f7f30d |
478 | This function will return an ANSI folder path if the long name cannot |
479 | be represented in the system codepage. Use Win32::GetLongPathName() |
480 | on the result of Win32::GetFolderPath() if you want the Unicode |
481 | version of the folder name. |
482 | |
b4ad57f4 |
483 | =item Win32::GetFullPathName(FILENAME) |
484 | |
485 | [CORE] GetFullPathName combines the FILENAME with the current drive |
486 | and directory name and returns a fully qualified (aka, absolute) |
487 | path name. In list context it returns two elements: (PATH, FILE) where |
488 | PATH is the complete pathname component (including trailing backslash) |
489 | and FILE is just the filename part. Note that no attempt is made to |
490 | convert 8.3 components in the supplied FILENAME to longnames or |
34f7f30d |
491 | vice-versa. Compare with Win32::GetShortPathName() and |
492 | Win32::GetLongPathName(). |
493 | |
494 | If supported by the core Perl version, this function will return an |
495 | ANSI path name if the full pathname cannot be represented in the |
496 | system codepage. |
b4ad57f4 |
497 | |
498 | =item Win32::GetLastError() |
499 | |
500 | [CORE] Returns the last error value generated by a call to a Win32 API |
501 | function. Note that C<$^E> used in a numeric context amounts to the |
502 | same value. |
503 | |
504 | =item Win32::GetLongPathName(PATHNAME) |
505 | |
506 | [CORE] Returns a representation of PATHNAME composed of longname |
507 | components (if any). The result may not necessarily be longer |
508 | than PATHNAME. No attempt is made to convert PATHNAME to the |
34f7f30d |
509 | absolute path. Compare with Win32::GetShortPathName() and |
510 | Win32::GetFullPathName(). |
511 | |
512 | This function may return the pathname in Unicode if it cannot be |
513 | represented in the system codepage. Use Win32::GetANSIPathName() |
514 | before passing the path to a system call or another program. |
b4ad57f4 |
515 | |
516 | =item Win32::GetNextAvailDrive() |
517 | |
518 | [CORE] Returns a string in the form of "<d>:" where <d> is the first |
519 | available drive letter. |
520 | |
521 | =item Win32::GetOSVersion() |
522 | |
523 | [CORE] Returns the list (STRING, MAJOR, MINOR, BUILD, ID), where the |
524 | elements are, respectively: An arbitrary descriptive string, the major |
525 | version number of the operating system, the minor version number, the |
526 | build number, and a digit indicating the actual operating system. |
527 | For the ID, the values are 0 for Win32s, 1 for Windows 9X/Me and 2 for |
528 | Windows NT/2000/XP/2003. In scalar context it returns just the ID. |
529 | |
530 | Currently known values for ID MAJOR and MINOR are as follows: |
531 | |
532 | OS ID MAJOR MINOR |
533 | Win32s 0 - - |
534 | Windows 95 1 4 0 |
535 | Windows 98 1 4 10 |
536 | Windows Me 1 4 90 |
537 | Windows NT 3.51 2 3 51 |
538 | Windows NT 4 2 4 0 |
539 | Windows 2000 2 5 0 |
540 | Windows XP 2 5 1 |
541 | Windows Server 2003 2 5 2 |
b76aa5af |
542 | Windows Vista 2 6 0 |
b4ad57f4 |
543 | |
544 | On Windows NT 4 SP6 and later this function returns the following |
545 | additional values: SPMAJOR, SPMINOR, SUITEMASK, PRODUCTTYPE. |
546 | |
547 | SPMAJOR and SPMINOR are are the version numbers of the latest |
548 | installed service pack. |
549 | |
550 | SUITEMASK is a bitfield identifying the product suites available on |
551 | the system. Known bits are: |
552 | |
553 | VER_SUITE_SMALLBUSINESS 0x00000001 |
554 | VER_SUITE_ENTERPRISE 0x00000002 |
555 | VER_SUITE_BACKOFFICE 0x00000004 |
556 | VER_SUITE_COMMUNICATIONS 0x00000008 |
557 | VER_SUITE_TERMINAL 0x00000010 |
558 | VER_SUITE_SMALLBUSINESS_RESTRICTED 0x00000020 |
559 | VER_SUITE_EMBEDDEDNT 0x00000040 |
560 | VER_SUITE_DATACENTER 0x00000080 |
561 | VER_SUITE_SINGLEUSERTS 0x00000100 |
562 | VER_SUITE_PERSONAL 0x00000200 |
563 | VER_SUITE_BLADE 0x00000400 |
564 | VER_SUITE_EMBEDDED_RESTRICTED 0x00000800 |
565 | VER_SUITE_SECURITY_APPLIANCE 0x00001000 |
566 | |
567 | The VER_SUITE_xxx names are listed here to crossreference the Microsoft |
568 | documentation. The Win32 module does not provide symbolic names for these |
569 | constants. |
570 | |
571 | PRODUCTTYPE provides additional information about the system. It should |
572 | be one of the following integer values: |
573 | |
574 | 1 - Workstation (NT 4, 2000 Pro, XP Home, XP Pro) |
575 | 2 - Domaincontroller |
576 | 3 - Server |
577 | |
578 | =item Win32::GetOSName() |
579 | |
82adc83d |
580 | In scalar context returns the name of the Win32 operating system |
b4ad57f4 |
581 | being used. In list context returns a two element list of the OS name |
582 | and whatever edition information is known about the particular build |
583 | (for Win9X boxes) and whatever service packs have been installed. |
584 | The latter is roughly equivalent to the first item returned by |
585 | GetOSVersion() in list context. |
586 | |
587 | Currently the possible values for the OS name are |
588 | |
589 | Win32s Win95 Win98 WinMe WinNT3.51 WinNT4 Win2000 WinXP/.Net Win2003 |
590 | |
591 | This routine is just a simple interface into GetOSVersion(). More |
592 | specific or demanding situations should use that instead. Another |
593 | option would be to use POSIX::uname(), however the latter appears to |
594 | report only the OS family name and not the specific OS. In scalar |
595 | context it returns just the ID. |
596 | |
597 | The name "WinXP/.Net" is used for historical reasons only, to maintain |
598 | backwards compatibility of the Win32 module. Windows .NET Server has |
599 | been renamed as Windows 2003 Server before final release and uses a |
600 | different major/minor version number than Windows XP. |
601 | |
602 | =item Win32::GetShortPathName(PATHNAME) |
603 | |
eb6bfc3a |
604 | [CORE] Returns a representation of PATHNAME that is composed of short |
605 | (8.3) path components where available. For path components where the |
606 | file system has not generated the short form the returned path will |
607 | use the long form, so this function might still for instance return a |
b3eb56ab |
608 | path containing spaces. Returns C<undef> when the PATHNAME does not |
609 | exist. Compare with Win32::GetFullPathName() and |
34f7f30d |
610 | Win32::GetLongPathName(). |
b4ad57f4 |
611 | |
612 | =item Win32::GetProcAddress(INSTANCE, PROCNAME) |
613 | |
82adc83d |
614 | Returns the address of a function inside a loaded library. The |
b4ad57f4 |
615 | information about what you can do with this address has been lost in |
616 | the mist of time. Use the Win32::API module instead of this deprecated |
617 | function. |
618 | |
619 | =item Win32::GetTickCount() |
620 | |
621 | [CORE] Returns the number of milliseconds elapsed since the last |
622 | system boot. Resolution is limited to system timer ticks (about 10ms |
623 | on WinNT and 55ms on Win9X). |
624 | |
e364e11c |
625 | =item Win32::GuidGen() |
626 | |
82adc83d |
627 | Creates a globally unique 128 bit integer that can be used as a |
e364e11c |
628 | persistent identifier in a distributed setting. To a very high degree |
629 | of certainty this function returns a unique value. No other |
630 | invocation, on the same or any other system (networked or not), should |
631 | return the same value. |
632 | |
633 | The return value is formatted according to OLE conventions, as groups |
634 | of hex digits with surrounding braces. For example: |
635 | |
636 | {09531CF1-D0C7-4860-840C-1C8C8735E2AD} |
637 | |
b4ad57f4 |
638 | =item Win32::InitiateSystemShutdown |
639 | |
640 | (MACHINE, MESSAGE, TIMEOUT, FORCECLOSE, REBOOT) |
641 | |
82adc83d |
642 | Shutsdown the specified MACHINE, notifying users with the |
b4ad57f4 |
643 | supplied MESSAGE, within the specified TIMEOUT interval. Forces |
644 | closing of all documents without prompting the user if FORCECLOSE is |
645 | true, and reboots the machine if REBOOT is true. This function works |
646 | only on WinNT. |
647 | |
648 | =item Win32::IsAdminUser() |
649 | |
82adc83d |
650 | Returns non zero if the account in whose security context the |
b4ad57f4 |
651 | current process/thread is running belongs to the local group of |
652 | Administrators in the built-in system domain; returns 0 if not. |
34f7f30d |
653 | On Windows Vista it will only return non-zero if the process is |
b3eb56ab |
654 | actually running with elevated privileges. Returns C<undef> |
655 | and prints a warning if an error occurred. This function always |
34f7f30d |
656 | returns 1 on Win9X. |
b4ad57f4 |
657 | |
658 | =item Win32::IsWinNT() |
659 | |
660 | [CORE] Returns non zero if the Win32 subsystem is Windows NT. |
661 | |
662 | =item Win32::IsWin95() |
663 | |
664 | [CORE] Returns non zero if the Win32 subsystem is Windows 95. |
665 | |
666 | =item Win32::LoadLibrary(LIBNAME) |
667 | |
82adc83d |
668 | Loads a dynamic link library into memory and returns its module |
34f7f30d |
669 | handle. This handle can be used with Win32::GetProcAddress() and |
670 | Win32::FreeLibrary(). This function is deprecated. Use the Win32::API |
b4ad57f4 |
671 | module instead. |
672 | |
673 | =item Win32::LoginName() |
674 | |
675 | [CORE] Returns the username of the owner of the current perl process. |
34f7f30d |
676 | The return value may be a Unicode string. |
b4ad57f4 |
677 | |
678 | =item Win32::LookupAccountName(SYSTEM, ACCOUNT, DOMAIN, SID, SIDTYPE) |
679 | |
82adc83d |
680 | Looks up ACCOUNT on SYSTEM and returns the domain name the SID and |
b4ad57f4 |
681 | the SID type. |
682 | |
683 | =item Win32::LookupAccountSID(SYSTEM, SID, ACCOUNT, DOMAIN, SIDTYPE) |
684 | |
82adc83d |
685 | Looks up SID on SYSTEM and returns the account name, domain name, |
b4ad57f4 |
686 | and the SID type. |
687 | |
688 | =item Win32::MsgBox(MESSAGE [, FLAGS [, TITLE]]) |
689 | |
82adc83d |
690 | Create a dialogbox containing MESSAGE. FLAGS specifies the |
b4ad57f4 |
691 | required icon and buttons according to the following table: |
692 | |
693 | 0 = OK |
694 | 1 = OK and Cancel |
695 | 2 = Abort, Retry, and Ignore |
696 | 3 = Yes, No and Cancel |
697 | 4 = Yes and No |
698 | 5 = Retry and Cancel |
699 | |
700 | MB_ICONSTOP "X" in a red circle |
701 | MB_ICONQUESTION question mark in a bubble |
702 | MB_ICONEXCLAMATION exclamation mark in a yellow triangle |
703 | MB_ICONINFORMATION "i" in a bubble |
704 | |
705 | TITLE specifies an optional window title. The default is "Perl". |
706 | |
707 | The function returns the menu id of the selected push button: |
708 | |
709 | 0 Error |
710 | |
711 | 1 OK |
712 | 2 Cancel |
713 | 3 Abort |
714 | 4 Retry |
715 | 5 Ignore |
716 | 6 Yes |
717 | 7 No |
718 | |
719 | =item Win32::NodeName() |
720 | |
721 | [CORE] Returns the Microsoft Network node-name of the current machine. |
722 | |
34f7f30d |
723 | =item Win32::OutputDebugString(STRING) |
724 | |
725 | Sends a string to the application or system debugger for display. |
726 | The function does nothing if there is no active debugger. |
727 | |
728 | Alternatively one can use the I<Debug Viewer> application to |
729 | watch the OutputDebugString() output: |
730 | |
731 | http://www.microsoft.com/technet/sysinternals/utilities/debugview.mspx |
732 | |
b4ad57f4 |
733 | =item Win32::RegisterServer(LIBRARYNAME) |
734 | |
82adc83d |
735 | Loads the DLL LIBRARYNAME and calls the function DllRegisterServer. |
b4ad57f4 |
736 | |
737 | =item Win32::SetChildShowWindow(SHOWWINDOW) |
738 | |
739 | [CORE] Sets the I<ShowMode> of child processes started by system(). |
740 | By default system() will create a new console window for child |
741 | processes if Perl itself is not running from a console. Calling |
742 | SetChildShowWindow(0) will make these new console windows invisible. |
743 | Calling SetChildShowWindow() without arguments reverts system() to the |
744 | default behavior. The return value of SetChildShowWindow() is the |
34f7f30d |
745 | previous setting or C<undef>. |
b4ad57f4 |
746 | |
82adc83d |
747 | The following symbolic constants for SHOWWINDOW are available |
b4ad57f4 |
748 | (but not exported) from the Win32 module: SW_HIDE, SW_SHOWNORMAL, |
749 | SW_SHOWMINIMIZED, SW_SHOWMAXIMIZED and SW_SHOWNOACTIVATE. |
750 | |
751 | =item Win32::SetCwd(NEWDIRECTORY) |
752 | |
753 | [CORE] Sets the current active drive and directory. This function does not |
754 | work with UNC paths, since the functionality required to required for |
755 | such a feature is not available under Windows 95. |
756 | |
757 | =item Win32::SetLastError(ERROR) |
758 | |
759 | [CORE] Sets the value of the last error encountered to ERROR. This is |
760 | that value that will be returned by the Win32::GetLastError() |
761 | function. |
762 | |
763 | =item Win32::Sleep(TIME) |
764 | |
765 | [CORE] Pauses for TIME milliseconds. The timeslices are made available |
766 | to other processes and threads. |
767 | |
768 | =item Win32::Spawn(COMMAND, ARGS, PID) |
769 | |
770 | [CORE] Spawns a new process using the supplied COMMAND, passing in |
771 | arguments in the string ARGS. The pid of the new process is stored in |
772 | PID. This function is deprecated. Please use the Win32::Process module |
773 | instead. |
774 | |
775 | =item Win32::UnregisterServer(LIBRARYNAME) |
776 | |
82adc83d |
777 | Loads the DLL LIBRARYNAME and calls the function |
b4ad57f4 |
778 | DllUnregisterServer. |
779 | |
780 | =back |
781 | |
782 | =cut |
