NAME
tvtohz, tstohz - translate time period to timeout delay
SYNOPSIS

int
tvtohz(const struct timeval *tv);
int
tstohz(const struct timespec *ts);
DESCRIPTION
The tvtohz() and tstohz() functions return the number of ticks in the
specified amount of time. If the return value would exceed the maximum
value representable by an int, it is capped at INT_MAX. They are mainly
used to translate a timeval or timespec, respectively, into a suitable
argument for tsleep(9).
CODE REFERENCES
These functions are implemented in the file sys/kern/kern_clock.c.
