_dos_getftime

Syntax

#include <dos.h>

unsigned int _dos_getftime(int handle, unsigned int *p_date, unsigned *p_time);

Description

This function gets the date and time of the given file and puts these values into p_date and p_time variable. The meaning of DOS date in the p_date variable is the following:

F   E   D   C   B   A   9   8   7   6   5   4   3   2   1   0  (bits)
X   X   X   X   X   X   X   X   X   X   X   X   X   X   X   X
*-----------------------*   *-----------*   *---------------*
        year                    month              day

year  = 0-119 (relative to 1980)
month = 1-12
day   = 1-31

The meaning of DOS time in the p_time variable is the following:

F   E   D   C   B   A   9   8   7   6   5   4   3   2   1   0
X   X   X   X   X   X   X   X   X   X   X   X   X   X   X   X
*---------------*   *-------------------*   *---------------*
      hours              minutes                seconds

hours   = 0-23
minutes = 0-59
seconds = 0-29 in two-second intervals

See section _dos_setftime.

Return Value

Returns 0 if successful and return DOS error on error (and sets errno=EBADF).

Example

unsigned int handle, date, time;

_dos_open("FOO.DAT", O_RDWR, &handle);
_dos_gettime(handle, &date, &time);
_dos_close(handle);
printf("FOO.DAT date and time is: %04u-%02u-%02u %02u:%02u:%02u.\n",
       /*       year                      month              day    */
       ((date >> 9) & 0x7F) + 1980U, (date >>  5) & 0x0F, date & 0x1F,
       /*       hour                minute           second         */
       (time >> 11) & 0x1F, (time >>  5) & 0x3F, (time & 0x1F) * 2);
