tvtohz, tstohz —

translate time period to timeout delay

SYNOPSIS

#include <sys/types.h>
#include <sys/time.h>
#include <sys/systm.h>

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.
