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  corresponding
       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 millisec-
       onds 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; other-
       wise, -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       This function may be withdrawn in a future version.
