dos_setftime

Usage

   #include <dos.h>

   int dos_setftime(int fd, unsigned date, unsigned time);

Description

   Sets the time and date of the file attatched to the file descriptor fd to
   those  specified in the arguments date and time. The format of these
   arguments is the same as those which are obtained by the use of the
   dos_getftime function.

   date:
           bits 0 to 4     day of month (0-31)
           bits 5 to 8     month (0-12)
           bits 9 to 15    year (relative to 1980)

   time:
           bits 0 to 4     no of 2 second increments (0-29)
           bits 5 to 10    minutes (0-59)
           bits 11 to 15   hours (0-23)

Example 


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

   int main()
   {
       int fd, d,m,y,h,mi,s;
       unsigned date, time;

       printf("Creating temporary file\n");
       fd = dos_creat("temp.fil",FA_RDONLY);
       if (fd == -1)
           {
           perror("Error opening file");
           exit(EXIT_FAILURE);
           }
       dos_getftime(fd,&date,&time);
       d = date & 0b11111;

       m = (date >> 5)  & 0b1111;
       y = ((date >> 9) & 0b1111111) + 1980;
       s = (time & 0b11111)*2;
       mi = (time >> 5)  & 0b111111;
       h = (time >> 11) & 0b11111;
       close(fd);
       printf("temp.fil date = %02d/%02d/%02d\n",m,d,y);
       printf("         time = %02d:%02d:%02d\n",h,mi,s);
       if (unlink("temp.fil") == 0)
           printf("\nTemporary file successfully deleted\n");
       else {
           perror("Error deleting file:");
           return EXIT_FAILURE;
       }
       return EXIT_SUCCESS;
   }

Return Value
