os_ns_to_timespec()

static void os_ns_to_timespec ( uint64_t  ns, struct timespec *  spec  )

inlinestatic

#include <auxiliary/os/os_time.h>

Convert an nanosecond integer to a timespec struct.

Note that this only does the value splitting, no adjustment for epochs is performed.

os_realtime_get_ns()

static uint64_t os_realtime_get_ns ( void  )

inlinestatic

#include <auxiliary/os/os_time.h>

Return a realtime clock in nanoseconds (Linux-only)

os_timespec_to_ns()

static uint64_t os_timespec_to_ns ( const struct timespec *  spec )

inlinestatic

#include <auxiliary/os/os_time.h>

Convert a timespec struct to nanoseconds.

Note that this only does the value combining, no adjustment for epochs is performed.

Referenced by os_monotonic_get_ns(), os_realtime_get_ns(), and os_semaphore::os_semaphore_get_realtime_clock().

os_timeval_to_ns()

static uint64_t os_timeval_to_ns ( struct timeval *  val )

inlinestatic

#include <auxiliary/os/os_time.h>

Convert a timeval struct to nanoseconds.
