BINTIME_ADD(9) BSD Kernel Developer's Manual BINTIME_ADD(9)
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 oppo-
site. The functions bintime2timeval() and timeval2bintime() operate with struct timeval instead. The result is stored to the right-hand
side.
