FTIME(3P)						     POSIX Programmer's Manual							 FTIME(3P)

PROLOG
       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

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       This function may be withdrawn in a future version.
