Re: [Dev-C++] Inline Assembly

[Per W. <pw...@ia...>]

First of all - to inline assembly using gcc, you should read this article:
http://www.ibiblio.org/gferg/ldp/GCC-Inline-Assembly-HOWTO.html
gcc uses Motorola-style assembly instructions, while your example is
using Intel-style assembly instructions.

Second: Most old assembly code you find on the net playing with graphics
and sound on the PC are only for 16-bit MS-Dos applications.

gcc produces 32-bit protected mode code, and then you can't access
hardware directly and most BIOS functions are not possible to use.

If you want to use gcc to create 32-bit console applications that accesses
the hardware I would recommend that you look at the old djgpp port of gcc.
It is a port that uses a dos extender and gives a lot of functionality
using DPMI and similar interfaces to either run together with QEMM or
similar on a MS-Dos machine or to interact with the Win32 OS. There are a
lot of code on the net that describes how to use the VESA standard to
access the graphics card - with or without assembler instructions.
