NAME
ts2timo —
convert time interval to tick
count
SYNOPSIS
#include <sys/timevar.h>
int
ts2timo(
clock_id
clock_id,
int flags,
struct timespec *ts,
int *timo,
struct timespec *start);
DESCRIPTION
The
ts2timo() function converts the time interval specified in
ts into the integral number of system ticks that would
elapse (including the current tick) and places the result in
timo. The interval type is specified in the
flags argument and can be either
TIMER_ABSTIME
or
TIMER_RELTIME
. If the interval is specified as an
absolute time, then the
clock_id clock is used to
convert it to a relative time. If the
start argument is
not
NULL
, then current time for the
clock_id clock is placed in that argument.
RETURN VALUES
On success
ts2timo() returns
0
. On
failure it returns
ETIMEDOUT
if interval computed was
0
or negative, and
EINVAL
if
ts->tv_usec field in the computed interval is out of
range, or the
clock_id argument is invalid.
