dos_settime

Usage

   #include <dos.h>
   int dos_settime(struct dos_time_t *time);

Description

   Sets the current system via a call to DOS function 0x2d (45) to the
   values passed in the structure pointed to by time. The format of this
   structure is as follows:

   struct dos_time_t

   {
       char    hour;           /* hours (0-23)       */
       char    minute;         /* minutes (0-59)     */
       char    second;         /* seconds (0-59)     */
       char    hsecond;        /* seconds/100 (0-99) */
   }

Example 

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

   int main()
   {
       struct dos_time_t time;
       char oh;

       dos_gettime(&time);
       printf("Time is %02d:%02d:%02d:%02d\n",

                time.hour,time.minute,time.second,time.hsecond);

       oh = time.hour;
       time.hour = 4;
       dos_settime(&time);
       dos_gettime(&time);
       printf("Time is %02d:%02d:%02d:%02d\n",
                 time.hour,time.minute,time.second,time.hsecond);

       time.hour = oh;
       dos_settime(&time);
       dos_gettime(&time);
       printf("Time is %02d:%02d:%02d:%02d\n",
                time.hour,time.minute,time.second,time.hsecond);
       return EXIT_SUCCESS;
   }

Return Value

   0 if successful, otherwise returns the DOS error code if the time passed

   was invalid.
