[Dev-C++] mouse programming in DOS with assemly

[Markella K. <chr...@fr...>]

Hi,
I've a code that is work with TurboC3.11 but I can not port to DevC++.
I want to program the mouse in assembly.
The TurboC code is here 
<http://web.axelero.hu/makihu/mouse/useMouseInTurboC.c>.
My try is here <http://web.axelero.hu/makihu/mouse/myTryInDevCpp.c> with 
the DevC++.

Welcome to the real world, where we use operating systems, and 
everything is done through system calls.
To handle the mouse directly you'll have to either do some low-level 
communication (using the PS/2, serial, USB ports), talk to the driver 
(maybe a VXD that exposes the mouse data to user-level applications), etc.

If you want to just handle the cursor of a pointing device, you can do 
it in serveral ways, depending on what libraries you chose. With the 
Win32 API you can use these functions:

Other libraries may give you higher levels of abstraction.

Sorry, the MinGW compiler used by Dev-C++ can't do MS-DOS applications. It
generates 32-bit Windows applications (command line, graphical or
servies).

The djgpp port of gcc can be used to write 32-bit extended MS-DOS
applications but thease are also using protected mode where the
application can't directly access the hardware.

For using 16-bit assembler access of the hardware you shouold continue
with old TurboC or similar.

By the way - why do you want to access the mouse using assembler? The
mouse is a slow input device, so there are no speed issues requiring
assembler instructions. Optimized assember can result in a smaller memory
footprint but the world have since quite some time moved away from the
640kB restrictions of MS-DOS and the mouse handling isn't directly a large
part of the memory requirements for a 32-bit application.

I have to do it in this way for the school.
Can I use DOS interrupts to solve this problem?

ps.: This <http://www.ana.sudani.co.uk/Programming/mouse.htm> solution 
would be great too.
