.Sh SYNOPSIS
|
|
.In sys/types.h
|
|
.In sys/timeb.h
|
|
.Ft int
|
|
.Fn ftime "struct timeb *tp"
|

.Sh DESCRIPTION
|
|
.Bf -symbolic
|
|
This interface is obsoleted by
|
|
.Xr gettimeofday 2 .
|
|
.Ef
|
|
.Pp
|
|
The
|
|
.Fn ftime
|
|
routine fills in a structure pointed to by its argument,
|
|
as defined by
|
|
.In sys/timeb.h :
|
|
.Bd -literal -offset indent
|
|
/*
|
|
* Structure returned by ftime system call
|
|
*/
|
|
struct timeb
|
|
{
|
|
time_t time;
|
|
unsigned short millitm;
|
|
short timezone;
|
|
short dstflag;
|
|
};
|
|
.Ed
|
|
.Pp
|
|
The structure contains the time since the epoch in seconds,
|
|
up to 1000 milliseconds of more-precise interval,
|
|
The kernel no longer maintains the timezone and dstflag info, so 0 is
|
|
always returned for these fields.
