1.5.18 Set Interrupt Vector
Entry Parameter: AH = 25H
AL = interrupt number
DS:BX = address of interrupt routine
Return Value: None
Example :
void TS_set_interrupt_vector(int vect,unsigned int ds,unsigned int dx)
{
regs.h.ah= 0x25;
regs.h.al= (unsigned char)vect;
segregs.ds=ds;
regs.x.dx=dx;
int86x(0x21,&regs,&regs,&segregs);
}
1.5.19 Get System Date
Entry Parameter: AH = 2AH
Return Value: CX = year (1980 - 2079)
DH = month (1 - 12)
DL = day (1 - 31)
AL = weekday (0 - 6)
Example :
void TS_get_date(int *year,int *month,int *day,int *week)
{
TD_int_dos1(0x2a,0,0,0);
*year = regs.x.cx;
*month = regs.h.dh;
*day = regs.h.dl;
*week = regs.h.al;
}
1.5.20 Set System Date
Entry Parameter: AH = 2BH
CX = year (1980 - 2079)
DH = month (1 - 12)
DL = day (1 - 31)
Return Value: AL = 0/FFH ; OK/Setting error
Example :
int TS_set_date(int year,int month,int day)
{
regs.h.ah = 0x2b;
regs.x.cx = year;
regs.h.dh = month;
regs.h.dl = day;
int86(0x21,&regs,&regs);
return((int)regs.h.al);
