* ALDEFS.H
|
|
*
|
|
* Header file for ArchiveLib 2.0
|
|
*
|
|
* Copyright (c) 1994-1996 Greenleaf Software, Inc.
|
|
* All Rights Reserved
|
|
*
|
|
* DESCRIPTION
|
|
*
|
|
* This is the setup file for ArchiveLib. Everyone else has to include
|
|
* it, because all of the macros defined in here help to control
|
|
* how the library operates. Normally you will never have to include
|
|
* this header file, because it is included by ARCLIB.H, and consequently,
|
|
* everyone else.
|
|
*
|
|
* MACROS
|
|
*
|
|
* These are all calculated automatically for supported compilers.
|
|
*
|
|
* AL_WINDOWS : This library can use some or all of the Windows API
|
|
* AL_FLAT_MODEL : This library is a 32 bit library
|
|
* AL_LARGE_DATA : Data uses 16:16 data pointer
|
|
* AL_SMALL_CODE : Code uses 16 bit function pointers
|
|
* AL_OS2 : Some day.
|
|
* AL_UNIX : Those days are gone!
|
|
* AL_KR : Non-ANSI C, like the portable c compiler
|
|
*
|
|
* AL_BUILDING_DLL : Building the Windows DLL
|
|
* AL_USING_DLL : Change all pointer args to FAR if set
|
|
* AL_USING_CRT_DLL :
|
|
* AL_VB : Building a Win16 DLL appropriate for VB 3.0
|
|
*
|
|
* AL_SYMANTEC : Compiler selection
|
|
* AL_BORLAND : Compiler selection
|
|
* AL_MICROSOFT : Compiler selection
|
|
* AL_WATCOM : Compiler selection
|
|
* AL_SUN4 : No more!
|
|
*
|
|
* AL_UNUSED_PARAMETER : A macro that lets me make warning messages
|
|
* about unused parameters in C programs go away.
|
|
*
|
|
* Based on those settings, we can set this:
|
|
*
|
|
* AL_WIN32 : This is NT or Win32s
|
|
*
|
|
* AL_WINDOWS AL_FLAT_MODEL
|
|
* Vanilla DOS NO NO
|
|
* Borland DPMI16 NO NO
|
|
* Borland DPMI32 NO YES
|
|
* Symantec DOSX NO YES
|
|
* Win32s YES YES
|
|
* Vanilla Windows YES NO
|
|
*
|
|
* Finally, we use those to create these things used in prototypes:
|
|
*
|
|
* AL_CLASS_TYPE : Sometimes "export", for classes in DLLs
|
|
* AL_PROTO : Sometimes "export", for functions in DLLs
|
|
* AL_DLL_FAR : Sometimes "far", for arguments being passed to DLLs
|
|
* AL_FUNCTION : Vanilla exported functions are "_export pascal"
|
|
* AL_CFUNCTION : Variable argument export functions are "_export cdecl"
|
|
* AL_EXPORT : Used to define export functions under Windows, only
|
|
* for examples and so on. _export for Win16, blank for
|
|
* Win32.
|
|
*
|
|
* PROTOTYPES:
|
|
*
|
|
*
|
|
* ENUMERATED TYPES:
|
|
*
|
|
* ALMonitorType : Used to indicate whether a monitor
|
|
* is watching objects or an entire job.
|
|
*
|
|
* ALWindowsMessageType : To indicate whether an object of
|
|
* class ALMonitor is supposed to be
|
|
* sending total byte counts or
|
|
* percentage complete ratios.
|
|
*
|
|
* ALErrors : The global list of errors.
|
|
*
|
|
* ALCase : Used by ALName to indicate case
|
|
* sensitivity/handling
|
|
*
|
|
* ALGreenleafCompressionLevels : The five levels used by ALGreenleafEngine.
|
|
*
|
|
* ALTraverseSetting : Used to indicate whether class
|
|
* ALWildCardExpander will traverse
|
|
* subdirectories when searching.
|
|
*
|
|
* ALStorageType : The type of a storage engine.
|
|
*
|
|
* ALCompressionType : The type of a compression engine.
|
|
*
|
|
* REVISION HISTORY
|
|
*
|
|
* May 26, 1994 1.0A : First release
|
|
*
|
|
* July 7, 1994 1.0B : Added an #ifdef for Watcom 9.5. It couldn't take
|
|
* a pragma that 10.0 was happy with.
|
|
*
|
|
* July 11, 1994 1.0B : Added the AL_EXPORT constant. This is mostly used
|
|
* for my examples.
|
|
*
|
|
* August 10, 1994 1.0B : Added AL_KR, AL_VB, AL_UNIX, AL_SUN4, and AL_GCC.
|
|
*
|
|
* January 12, 1995 1.01B : Added AL_UNUSED_PARAMETR.
|
|
*
|
|
* February 14, 1996 2.0A : New release
