>Description:
According to the documentation (https://man.netbsd.org/clock_gettime.2), CLOCK_THREAD_CPUTIME_ID is supported by clock_getres. However, when using clock_getres with the CLOCK_THREAD_CPUTIME_ID clock ID, the function returns -1 and sets errno to EINVAL.
>How-To-Repeat:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main() {
    struct timespec res;

    if (clock_getres(CLOCK_THREAD_CPUTIME_ID, &res) == -1) {
        perror("clock_getres");
        return EXIT_FAILURE;
    }

    printf("Resolution of CLOCK_THREAD_CPUTIME_ID: %ld.%09ld seconds\n", res.tv_sec, res.tv_nsec);

    return EXIT_SUCCESS;
}
