Linux 2.6 - man page for ftime (linux section 3posix)

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 (par-
       ticularly 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 val-
       ues 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       This function may be withdrawn in a future version.
