void *LeesSensoren(void *threadid)
{
    struct displaygegevens *dg
    ...
    dg = (struct displaygegevens *)malloc(sizeof(struct displaygegevens));
    ...
    return (void*)dg;
}

void x()
{
    struct displaygegevens *dg

    pthreadcreate(&threads[t],NULL , &LeesSensoren, &threadid[t]);
    ...
    pthread_join(threads[t], (void **)&dg);
    rookstatus = dg->rookstatus;
    gasstatus = dg->gasstatus;
    temperatuur = dg->temperatuur;

    free(dg);
}

Something like that.
