ftime − return date and time
#include <sys/timeb.h>
int ftime(struct timeb *tp);
Return current date and time in tp, which is declared as following:
struct timeb {
|
time_t time; | ||
|
unsigned short millitm; | ||
|
short timezone; | ||
|
short dstflag; |
};
The structure contains the time since the epoch in seconds, up to 1000 milliseconds of more-precise interval, the local time zone (measured in minutes of time westward from Greenwich), and a flag that, if nonzero, indicates that Daylight Saving time applies locally during the appropriate part of the year.
This function always returns 0.
Under libc4 and libc5 the millitm field is meaningful. But glibc2 is buggy and returns 0 there; glibc 2.1.1 is correct again.
The ftime function appeared in 4.2BSD.
BSD 4.2
This call is obsoleted by gettimeofday(2).
