Answer 1

#include <stdio.h>
#include <time.h>

enum {SECS_TO_SLEEP = 4, NSEC_TO_SLEEP = 60};

int main() {
    struct timespec remaining, request = {SECS_TO_SLEEP, NSEC_TO_SLEEP};

    for (int i = 0; i < 10; i++) {
        printf("i - %d\n", i);
        if (i == 5) {
            printf("wait sleeping...\n");
            nanosleep(&request, &remaining);
        }
    }

    return 0;
}




/*
