- Turbo C++ XMS Interface Library
- by Richard Vuduc
- Version 1.1
-
- Copyright 1990, Richard Vuduc
- -------------------------------
-
- Well, I'm glad to see you followed directions and are now
- 'reading.me'. Here's a list of files included in this package
- (XMSCPP11.ZIP):
-
- - XMSCPPS.LIB // Turbo C++ linkable routines for accessing
- extended memory (small model).
- - XMSCPPL.LIB // Turbo C++ linkable routines for accessing
- extended memory (large model).
- - XMSHRW.CPP // Src for Get/Store routines (XMSHandle)
- - XMS.H // Turbo C++ XMS header file
- - XMSHNDL.H // XMSHandle Class Header file
- - README.TXT // That would be this file
- - XMSCPP.TXT // Documentation on how to use the library
- - XMSDEMO.CPP // Library demonstration program source code
- - XMSDEMO.EXE // Library demonstration executable
- - XMSDEMO2.CPP // Demonstration file 2 (XMSHandle Class)
- - XMSDEMO2.EXE // Demonstration file 2 executable
-
- Hardware and Software Requirements:
- -----------------------------------
- You need a 286 or above IBM AT compatible, enough conventional memory
- to run the Turbo C++ compiler, and 64k of extended memory to run the
- first demonstration program (XMSDEMO.EXE). The 2nd demo program
- (XMSDEMO2.EXE) has the same requirements.
-
- You also need to install HIMEM.SYS. I haven't worked out any
- distribution agreements with Microsoft, but you can get it from them
- in HIMEM.ARC on MSSYS on CompuServe. HIMEM is also bundled with
- Microsoft Windows 286 and MS Windows 3.0 (I don't know about Windows
- 386, but I imagine it's in there, too).
-
- Usage:
- ------
- You can reach me about any technical problems or any comments on
- improvements at my CIS Account: Richard Vuduc, 70022,1332.
-
- To link this library with your programs, just type:
- 'tcc -mz xxxxx.cpp xmscppz.lib'
- ^ ^
- Notice that I've marked that 'z' in 'xmscppz.lib' and '-mz'. You
- should replace this 'z' with the letter that corresponds to the
- correct library model (currently, the (s)mall and (l)arge models are
- supported. I hope to get the other models, and the source, out
- real soon now. The demo programs were compiled in the small
- model).
-
- So, to compile the demonstration program, just type:
- 'tcc -ms xmsdemo.cpp xmscpps.lib' <== for the small model
- 'tcc -ml xmsdemo.cpp xmscppl.lib' <== for the large model
-
- You can also link xmscpp[S|L].lib into the standard library. See
- the Turbo C++ manual for details.
-
- I encourage you to give me any comments on the lib. By doing that,
- you help ensure that I'll keep at it, with even BIGGER and GREATER
- things... Also, there is NO fee, but any contributions to a
- starving, young programmer would be most appreciated.
-
- To run the first demo, just type 'xmsdemo' and the program will go
- through a whole bunch of checks. It will read from and write to
- extended memory, and the High Memory Area.
-
- To run the second demo, just type 'xmsdemo2.' The program will fill
- three 4K blocks of extended memory with the letters 'a', 'b', and
- 'c', and then display play them on screen. After a screen has been
- filled with letters, strike any key to move on to the next screen.
- You will notice a slight delay while the program stuffs the extended
- memory blocks, but bear with it. As a test, you can play around with
- the cache size (see source and documentation) and see the performance
- differences with the different sizes.
-
- Things to Come...
- -----------------
- I hate to make this thing into vapor ware and spill the beans on my
- future plans, so I won't. I still haven't added support for the
- Upper Memory Block functions HIMEM provides, and I know those are
- worth implementing. If there's something else YOU'D like to see in
- this library, ASK FOR IT.
