_dos_gettime, _dos_settime

Gets and sets system time.

Defined in header <dos.h>

Syntax

#include <dos.h>
void _dos_gettime(struct dostime_t *timep);
unsigned  _dos_settime(struct dostime_t *timeip);

Portability

Remarks

_dos_gettime fills in the clostime_t structure pointed to by timep with the system's current time.

_dos_settime sets the system time to the values in the dostime_t structure pointed to by timep.

The dostime_t structure is defined as follows:

struct dostime_t {

unsigned char minute; /* minutes 0-59 */ unsigned char second; /* seconds 0-59 */ unsigned char hsecond; /* hundredths of seconds 0-99 */ };

Return value

_dos_gettime does not return a value.

If _dos_settime is successful, it returns 0. Otherwise, it returns the DOS error code, and the global variable errno is set to the following:

EINVAL Invalid time

Example

#include <stdio.h>
#include <dos.h>

int main (void) /* Example  for _dos_gettime. */
{
   struct dostime_t t;
   _dos_gettime(&t) ;
   printfC'The current time  is: %2d:%02d:l02d.%02d\n", t.hour, t.minute,
           t.second, t.hsecond);
   return 0;

#include <dos.h>
#include <process.h>
#include <stdio.h>

int main (void) /* Example  for _dos_settime. */
{
   struct dostime_t reset;
   reset.hour    = 17;
   reset.minute  =
   reset.second  = 0;
   reset.hsecond =
printf( "Setting time to 5 PM.\n"l
_dos_settime(&reset) ;
system ("time");
return 0;
