#include "libue.h"

int main() {

    re = ue_init_listener(&listener);
    if (re < 0) {
        fprintf(stderr, "Failed to initilize libue listener, err: %d\n", re);
        return -1;
    }

    /* blocking call */
    while ((re = ue_wait_for_event(&listener, &uev)) == 0) {
        switch (uev.action) {
        case UEVENT_ACTION_ADD:
            printf("Device %s added.", uev.devpath);
            break;
        case UEVENT_ACTION_REMOVE:
            printf("Device %s removed.", uev.devpath);
            break;
