Notes
This module contains a couple of time-related definitions, that are based on a hardware counter.
Include
ao_count.h |
Constants
AO_INFINITY
#define AO_INFINITY (AO_COUNT_MAX)
Infinity.
AO_TIME_MAX
AO_TIME_MIN
#define AO_TIME_MAX (AO_COUNT_MAX)
#define AO_TIME_MIN (AO_COUNT_MIN)
The maximum and minimum time value, respectively.
Types
ao_time_t
typedef ao_count_t ao_time_t;
This type is an alias for the ao_count_t type. It represents both time points and time spans. Because the underlying type is an unsigned integer type, negative time spans cannot be represented.
Functions
ao_now
#define ao_now() \
( \
ao_count() \
)
Gets the current time point.
AO_DAYS
AO_HOURS
AO_MINUTES
AO_SECONDS
AO_MILLISECONDS
AO_MICROSECOND
AO_NANOSECONDS
#define AO_DAYS(x) ((x) * (AO_COUNT_FREQUENCY) * (86400))
#define AO_HOURS(x) ((x) * (AO_COUNT_FREQUENCY) * (3600))
#define AO_MINUTES(x) ((x) * (AO_COUNT_FREQUENCY) * (60))
#define AO_SECONDS(x) ((x) * (AO_COUNT_FREQUENCY))
#define AO_MILLISECONDS(x) ((x) * (AO_COUNT_FREQUENCY) / (1000))
#define AO_MICROSECONDS(x) ((x) * (AO_COUNT_FREQUENCY) / (1000000))
#define AO_NANOSECONDS(x) ((x) * (AO_COUNT_FREQUENCY) / (1000000000))
Converts a time span to an ao_time_t value.

#define AO_NANOSECONDS_FROM_TIME(x) ((x) * (1000000000) / (AO_COUNT_FREQUENCY))
Converts a time span from an ao_time_t value.
