struct timespec;
(since C11)Structure holding an interval broken down into seconds and nanoseconds.
[edit] Member objects Member Description time_ttv_sec whole seconds (valid values are >= â0â) /* see below */ tv_nsec nanoseconds (valid values are [â0â, 999999999])
The type of tv_nsec is long.
The type of tv_nsec is an implementation-defined signed integer type that can represent integers in [â0â, 999999999].
The declaration order of tv_sec and tv_nsec is unspecified. Implementation may add other members to struct timespec.
The type of tv_nsec is long long on some platforms, which is conforming only since C23.
#include <stdint.h>
#include <stdio.h>
#include <time.h>
int main(void)
{
struct timespec ts;
timespec_get(&ts, TIME_UTC);
char buff[100];
strftime(buff, sizeof buff, "%D %T", gmtime(&ts.tv_sec));
printf("Current time: %s.%09ld UTC\n", buff, ts.tv_nsec);
printf("Raw timespec.tv_sec: %jd\n", (intmax_t)ts.tv_sec);
printf("Raw timespec.tv_nsec: %09ld\n", ts.tv_nsec);
}
Possible output:
Current time: 04/04/24 14:45:17.885909786 UTC Raw timespec.tv_sec: 1712241917 Raw timespec.tv_nsec: 885909786[edit] References
