ftime: získat datum a čas (ZASTARALÉ)

Originální popis anglicky: ftime - get date and time ( LEGACY)

Návod, kniha: POSIX Programmer's Manual

STRUČNĚ

#include <sys/timeb.h>
 
 
int ftime(struct timeb * tp);
 

POPIS / INSTRUKCE

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.

NÁVRATOVÁ HODNOTA

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

CHYBY / ERRORY

No errors are defined.
The following sections are informative.

PŘÍKLADY POUŽITÍ

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This function may be withdrawn in a future version.
