Initialize the mouse pointer in turbo c/c++ compiler

Hi,Friends i want to show that how to initialize mouse in c language and in turbo c/c++ compiler

code is here.

#include < stdio.h >
#include < conio.h >
#include < dos.h >
union REGS in , out;
void mouse_setposi(int * xpos, int * ypos)
{
    in .x.ax = 4; in .x.cx = * xpos; in .x.dx = * ypos;
    int86(51, & in , & out);
}
int mouse_callmouse()
{
    in .x.ax = 1;
    int86(51, & in , & out);
    return 1;
}
void main()
{
    int a, b, xpos, ypos, click;
    clrscr();
    a = 300;
    b = 80;
    mouse_setposi( & a, & b);
    mouse_callmouse();
    getch();
}

Now copy this code and paste into any .c file and save in "C:\TURBOC3\BIN" directory and you can download zip file that have already a .c file paste it into directory. after that open turbo c/c++ compiler and open this file and run ... :)
