Got LPT port to work, but mouse still is confusing, please help.

[CNewbie]

I got the lpt port to work, if anybody cares, heres some code.


#define LPT 0x0378
#define LCD_DATA_ADDRESS LPT+0
#define LCD_CONTROL_ADDRESS LPT+2

if ((ioperm (LPT, 3, 1)) == -1) {
printf ("init: failed\n"
} //set port to "ok i can write to it"
outportb(LCD_CONTROL_ADDRESS,0x17); //E2=1, RS=1, R/W=0, E=0
outportb(LCD_CONTROL_ADDRESS,0x0F); //E2=0, RS=1, R/W=0, E=0
outportb(LCD_CONTROL_ADDRESS,0x0D); //E2=0, RS=1, R/W=1, E=0

but the mouse still is confusing, i know i can fseek the /dev/mouse file but, I cant tell what and where the data is , you cant open it with a text viewer to see the data or its structure, so where do i start?
all i care about is DIRECTION and VELOCITY and LEFT_CLICK.
can someone post some code they may have written, or point me to a low-lwvwl mouse only faq,

I just need the Linux equavilant to:
#include <dos.h>

void get_mouse_mickeys()
{
//get mickey x and y
i.x.ax=11;
int86(0x33,&i,&o);
mickeyx=o.x.cx;
mickeyy=o.x.dx;
if (mickeyx>32000)mickeyx=(0-(65536-mickeyx));
if (mickeyy>32000)mickeyy=(0-(65536-mickeyy));

//get x and y cords and button state
i.x.ax=3;
int86(0x33,&i,&o);
mouse_x=o.x.cx;
mouse_y=o.x.dx;
mouse_b= o.x.bx;
}

Thank you for any help in advance.
