TS2TIMO(9)                 Kernel Developer's Manual                TS2TIMO(9)

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.
