Function that returns multiple elements

Question

I have a doubt in the following exercise:

Make a subroutine that takes a single value representing seconds. This subroutine should convert it to hours, minutes and seconds. All variables should be passed as a parameter, with no global variables.

#include <stdio.h>
#include <stdlib.h>

int ConverterSegundos(int seg) {
    int hr, min, segundos, res[3];

    res[0] = hr = (seg / 60) / 60; //Calculo das horas
    res[1] = min = (seg / 60) % 60; //Calculo dos minutos
    res[2] = segundos = seg % 60; //Calculo dos segundos

    return res[0];
}

int main(int argc, char** argv) {
    int segundos,horario[3];

    printf("Digite os segundos: ");
    scanf("%d", &segundos);
    horario[0] = ConverterSegundos(segundos);

    printf("Conversão para o formato %d:mm:ss \n",horario[0]);

    return (EXIT_SUCCESS);
}

The problem comes at the time of returning the values, as are 3 values thought to store them in a vector with 3 positions and return it,good the problem that I am not able to do this. I don’t know how to print each position individually of the returned vector.

NOTE: I haven’t seen any pointers yet.
