# NAME

`bintime_add` —
operations on “bintime”

# SYNOPSIS

`#include <sys/time.h>`

vid
`bintime_add`(struct bintime *bt, const struct bintime *bt2);

void
`bintime_addx`(struct bintime *bt, uint64_t x);

void
`bintime_sub`(struct bintime *bt, const struct bintime *bt2);

void
`bintime2timespec`(const struct bintime *bt, struct timespec *ts);

void
`timespec2bintime`(const struct timespec *ts, struct bintime *bt);

void
`bintime2timeval`(const struct bintime *bt, struct timeval *tv);

void
`timeval2bintime`(const struct timeval *tv, struct bintime *bt);

# DESCRIPTION

These functions are provided for convenience as part of the machine-independent timecounter(9) framework. All of them operate with the bintime structure.

The function `bintime_add`() adds the time information stored in bt2 to bt. Conversely, `bintime_sub`() subtracts bt2 from bt. The `bintime_addx`() function stores the fraction of a second x to bt.

Like the function names bespeak, `bintime2timespec`() converts the bintime structure to struct timespec and `timespec2bintime`() does the opposite. The functions `bintime2timeval`() and `timeval2bintime`() operate with struct timeval instead. The result is stored to the right-hand side.
