Answer 1

Create a pointer to a struct like you do in the first case above:

//create a pointer to a struct of type data and allocate memory to it
struct data *info
info = malloc(sizeof(struct data));

//set its fields
info->palabra   = ...;
info->directoro = ...;

//call pthread_create casting the struct to a `void *`
pthread_create ( &thread_id[i], NULL, &hilos_hijos, (void *)data);
