中断

 

中断处理函数

 

编写中断处理函数需要指定interrupt以表示这是一个中断处理函数。如果没有指定interrupt，它就是一个普通的函数。

 

void interrupt <interrupt routine>()
{
  ... 
  ...
  ...
}

 

中断处理函数如上面指定了interrupt的函数反编译后的代码大概是这样的：

 

<interrupt routine>	proc	far
	push	ax
	push	bx
	push	cx
	push	dx
	push	es
	push	ds
	push	si
	push	di
	push	bp
	mov	bp,DGROUP
	mov	ds,bp
	mov	bp,sp
   
        ...
        ...
        ...

	pop	bp
	pop	di
	pop	si
	pop	ds
	pop	es
	pop	dx
	pop	cx
	pop	bx
	pop	ax
	iret	
<interrupt routine>	endp

 

 

void interrupt kl_iroutine_0x32()
{
  printf("hello, world!\n");
}

void main()
{
    union REGS regs;

    disable();
    setvect(0x32, kl_iroutine_0x32);
    enable();


	int86(0x32, &regs, &regs);
	int86(0x32, &regs, &regs);
	int86(0x32, &regs, &regs);

    getch();
}

 

注册BGI驱动

int        _Cdecl registerbgidriver(void (*driver)(void));

注册的BGI驱动函数原型：

void (*driver)(void)

一些BGI驱动函数：

void           _Cdecl CGA_driver(void);
void           _Cdecl EGAVGA_driver(void);
void           _Cdecl IBM8514_driver(void);
void           _Cdecl Herc_driver(void);
void           _Cdecl ATT_driver(void);
void           _Cdecl PC3270_driver(void);

5554 bytes from 'EGAVGA.BGI' converted into 'EGAVGA.OBJ',

在C:\TURBOC3\BGI下生成了一个EGAVGA.OBJ文件。

viewport

#include<graphics.h>

void main()
{
    //int gd = DETECT;
    //int gm;

    int gd = DETECT;
    int gm = VGAHI; // VGAHI      = 2,  /* 640x480 16 color 1 page     */

    registerbgidriver(EGAVGA_driver);

    initgraph(&gd, &gm, "C:\\TURBOC3\BGI");
  
    setbkcolor(BLACK);

    setviewport(100, 100, 540, 380, 0);

    setcolor(WHITE);
    setfillstyle(1, WHITE);
    rectangle(0, 0, 440, 280); 
    floodfill(50, 50, WHITE);

	//clearviewport();

    setviewport(150, 150, 590, 430, 0);

    setcolor(GREEN);
    setfillstyle(1, LIGHTGRAY);
    rectangle(0, 0, 440, 280); 
    floodfill(50, 50, GREEN);

    //clearviewport();

    setviewport(180, 180, 620, 460, 0);

    setcolor(WHITE);
    setfillstyle(1, BLUE);
    rectangle(0, 0, 440, 280); 
    floodfill(50, 50, WHITE);

	//clearviewport();

    getch();
    closegraph();
}

 

 

 

 

#include<GRAPHICS.H>
void main()
{
    int gd = DETECT;
    int gm;

    registerbgidriver(EGAVGA_driver);

    initgraph(&gd, &gm, "C:\\TURBOC3\BGI");
  
    setbkcolor(12);
  
    setcolor(2);
    putpixel(10, 10, 1);
  
    getch();
    closegraph();
}

这里注册的BGI驱动EGAVGA_driver

 

 

void           _Cdecl EGAVGA_driver(void);

 

 

 

是在上面将BGI转换为OBJ（>BGIOBJ EGAVGA）的时候生成的：

public name = '_EGAVGA_driver'.

    int gm = VGAHI; // VGAHI      = 2,  /* 640x480 16 color 1 page     */

    registerbgidriver(EGAVGA_driver);

    initgraph(&gd, &gm, "C:\\TURBOC3\BGI");
  
    setbkcolor(12);
  
    setcolor(2);
    setlinestyle(SOLID_LINE, EMPTY_FILL, 0 /*NORM_WIDTH*/);

    rectangle(10, 10, 640 - 10, 480 - 10);

    getch();
    closegraph();
}
