Synopsis:
#include <dos.h>
unsigned _dos_settime( struct dostime_t *time );
struct dostime_t {
unsigned char hour; /* 0-23 */
unsigned char minute; /* 0-59 */
unsigned char second; /* 0-59 */
unsigned char hsecond; /* 1/100 second; 0-99 */
};
Description:
The _dos_settime function uses system call 0x2D to set the current
system time. The time information is passed in a dostime_t structure
pointed to by time.
Returns:
The _dos_settime function returns zero if successful. Otherwise, it
returns a non-zero value and sets errno to EINVAL indicating that an
invalid time was given.
Example:
#include <stdio.h>
#include <dos.h>
void main()
{
struct dosdate_t date;
struct dostime_t time;
/* Get and display the current date and time */
_dos_getdate( &date );
_dos_gettime( &time );
printf( "The date (MM-DD-YYYY) is: %d-%d-%d\n",
date.month, date.day, date.year );
printf( "The time (HH:MM:SS) is: %.2d:%.2d:%.2d\n",
time.hour, time.minute, time.second );
/* Change it to the turn of the century */
date.year = 1999;
date.month = 12;
date.day = 31;
time.hour = 23;
time.minute = 59;
_dos_setdate( &date );
_dos_settime( &time );
printf( "New date (MM-DD-YYYY) is: %d-%d-%d\n",
date.month, date.day, date.year );
printf( "New time (HH:MM:SS) is: %.2d:%.2d:%.2d\n",
time.hour, time.minute, time.second );
}
produces the following:
The date (MM-DD-YYYY) is: 12-25-1989
The time (HH:MM:SS) is: 14:23:15
New date (MM-DD-YYYY) is: 12-31-1999
New time (HH:MM:SS) is: 23:59:16
