Below is the C program display Mouse Pointer in graphics mode. Here we have used 2 functions to achieve it.
int initmouse() : function is used to intialize the mouse pointer. Which returns int value. Value 0 indicates Mouse support is not available.
void showmousepointer() : function is used to show mouse pointer. Which does not return any value.
int initmouse() : function is used to intialize the mouse pointer. Which returns int value. Value 0 indicates Mouse support is not available.
void showmousepointer() : function is used to show mouse pointer. Which does not return any value.
Code:
#include
#include
#include
int initmouse();
void showmousepointer();
union REGS i, o;
main()
{
int status, gd = DETECT, gm;
initgraph(&gd,&gm,"C:\\TC\\BGI");
status = initmouse();
if ( status == 0 )
printf("Mouse support not available.\n");
else
showmousepointer();
getch();
return 0;
}
int initmouse()
{
i.x.ax = 0;
int86(0X33,&i,&o);
return ( o.x.ax );
}
void showmousepointer()
{
i.x.ax = 1;
int86(0X33,&i,&o);
}
