1.4.4 Get Cursor Position
Entry Parameter: AH = 3 ;
Return Value: DH = Row
DL = Column
Example :
void TL_getxy(int *x,int *y)
{
regs.h.ah = 3;
int86(0x10,&regs,&regs);
*y = regs.h.dh;
*x = regs.h.dl;
}
1.4.5 Display 16x16 Bitmap
Entry Parameter: AH = 4
DH = Row
DL = Column
DS:BX ; pointer to bitmap ( 32-bytes pattern data )
Return Value: None
Note: This function is available only in large font.
Example :
void TL_display_16x16_location(int x,int y,unsigned char *str)
{
regs.h.ah=4;
regs.h.dh=(unsigned char)y;
regs.h.dl=(unsigned char)x;
segregs.ds = FP_SEG(str);
regs.x.bx = FP_OFF(str);
int86x(0x10,&regs,&regs,&segregs);
}
