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 calculate the corresponding 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, and places the computed number of ticks in the integer referenced by timo. On failure it returns ETIMEDOUT if interval computed was 0 or negative, or EINVAL if the ts->tv_nsec field is out of range, or the clock_id argument is invalid, or if computing the relative time from a supplied absolute value would cause an arithmetic overflow.

HISTORY

The ts2timo function first appeared in NetBSD 7.0.
