.Dd May 22, 2013 .Dt TS2TIMO 9 .Os .Sh NAME .Nm ts2timo .Nd convert time interval to tick count .Sh SYNOPSIS n sys/timevar.h .Ft int .Fn ts2timo "clock_id clock_id" "int flags" "struct timespec *ts" "int *timo" "struct timespec *start" .Sh DESCRIPTION The .Fn ts2timo function converts the time interval specified in .Fa ts into the integral number of system ticks that would elapse (including the current tick) and places the result in .Fa timo . The interval type is specified in the .Fa flags argument and can be either .Dv TIMER_ABSTIME or .Dv TIMER_RELTIME . If the interval is specified as an absolute time, then the .Fa clock_id clock is used to calculate the corresponding relative time. If the .Fa start argument is not .Dv NULL , then current time for the .Fa clock_id clock is placed in that argument. .Sh RETURN VALUES On success .Fn ts2timo returns .Dv 0 , and places the computed number of ticks in the integer referenced by .Fa timo . On failure it returns .Er ETIMEDOUT if interval computed was .Dv 0 or negative, or .Er EINVAL if the .Fa ts->tv_nsec field is out of range, or the .Fa clock_id argument is invalid, or if computing the relative time from a supplied absolute value would cause an arithmetic overflow. .Sh SEE ALSO .Xr clock_gettime 2 , .Xr clock_nanosleep 2 .Sh HISTORY The .Nm function first appeared in .Nx 7.0 .
