ftime - get date and time (
LEGACY)
Návod, kniha: POSIX Programmer's Manual
#include <sys/timeb.h>
int ftime(struct timeb *
tp);
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.
Upon successful completion, the
ftime() function shall return 0;
otherwise, -1 shall be returned.
No errors are defined.
The following sections are informative.
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);
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().
None.
This function may be withdrawn in a future version.
