FTIME(P)                   POSIX Programmer's Manual                  FTIME(P)



NAME
       ftime - get date and time (LEGACY)

SYNOPSIS
       #include <sys/timeb.h>

       int ftime(struct timeb *tp);


DESCRIPTION
       The ftime() function shall set the time and millitm members of the
       timeb structure pointed to by tp to contain the seconds and
       milliseconds portions, respectively, of the current time in seconds
       since the Epoch. The contents of the timezone and dstflag members of tp
       after a call to ftime() are unspecified.

       The system clock need not have millisecond granularity. Depending on
       any granularity (particularly a granularity of one) renders code non-
       portable.

RETURN VALUE
       Upon successful completion, the ftime() function shall return 0;
       otherwise, -1 shall be returned.

ERRORS
       No errors are defined.

       The following sections are informative.

EXAMPLES
   Getting the Current Time and Date
       The following example shows how to get the current system time values
       using the ftime() function. The timeb structure pointed to by tp is
       filled with the current system time values for time and millitm.


              #include <sys/timeb.h>


              struct timeb tp;
              int          status;
              ...
              status = ftime(&tp);

APPLICATION USAGE
       For applications portability, the time() function should be used to
       determine the current time instead of ftime(). Realtime applications
       should use clock_gettime() to determine the current time instead of
       ftime().

RATIONALE
       None.

FUTURE DIRECTIONS
       This function may be withdrawn in a future version.
