Convert a kernel timeout to a timespec.
This function converts time durations expressed as Zephyr k_timeout_t objects to struct timespec
objects.

#include <include/zephyr/sys/timeutil.h>
Convert a timespec to a kernel timeout.
This function converts durations expressed as a struct timespec
to Zephyr k_timeout_t objects.
Given that the range of a struct timespec
is much larger than the range of k_timeout_t, and also given that the functions are only intended to be used to convert time durations (which are always positive), the function will saturate to K_NO_WAIT if the tv_sec
field of ts is negative.
Similarly, if the duration is too large to fit in k_timeout_t, the function will saturate to K_FOREVER.
ts | the timespec to convert |
#include <include/zephyr/sys/timeutil.h>
Convert broken-down time to a POSIX epoch offset in seconds.
tm | pointer to broken down time. |
(time_t)-1 is returned and errno
is set to ERANGE`
.#include <include/zephyr/sys/timeutil.h>
Convert broken-down time to a POSIX epoch offset in seconds.
tm | pointer to broken down time. |
