Well after some reading I must confess I'm still a little bit lost.
According to what I've figured out, this should work:


#include <stdio.h>
#include <unistd.h>
#include <libebook/e-book.h>
#include <libebook/e-contact.h>
#include <libecal/e-cal.h>
#include <libecal/e-cal-time-util.h>
#include <libbonobo-2.0/libbonobo.h>


gboolean end_program=FALSE;

ECal* open_calendar() {
  ECal* cal;
  GError* error = 0;
  cal = e_cal_new_system_calendar();
  e_cal_open(cal, FALSE, &error);
  if (error)
    printf("ERROR!");
  return cal;
}

static void get_all_appointments() {
  GError* error = 0;
  GList* appts, *l;
  ECal* cal = open_calendar();
  e_cal_get_object_list_as_comp(cal, "#t", &appts, &error);
  if((error)||( e_cal_get_load_state (cal) !=   E_CAL_LOAD_LOADED))
    printf("ERROR\n");
  for (l = appts; l;l = l->next) {
    ECalComponent *ev_appt = E_CAL_COMPONENT(l->data);
    g_object_unref(ev_appt);
  }
  g_list_free(appts);
  g_object_unref(cal);   
}

gboolean cb_work(void *data)
{
  get_all_appointments();
  bonobo_main_quit(); 
  return FALSE;
}


int main(int argc, char** argv) {

  g_type_init();
  bonobo_init(&argc,argv);
  bonobo_activate();
 
  if(bonobo_is_initialized())
    printf("Init (pid %i)\n", getpid());
  g_idle_add(cb_work, NULL); 
  bonobo_main();
  bonobo_debug_shutdown();
  if(!bonobo_is_initialized())
    printf("Not init!\n");
  return 0;
}


but the truth is that it still displays the "waiting for completion"
message :-(. If I execute bonobo_main_quit in a timeout callback only
after cb_work gets executed, it does work, but I guess it's just like
if it's doing a sleep.  I feel I'm missing something terribly obvious
but I can't figure out what.

 Anyway, from the post I previously referred [1] it seems like it
shouldn't need to run bonobo_main (and in fact, retrieving the
appointments, etc, runs fine even if there is no bonobo_main),
although the post could be outdated as of now. Maybe some of the
internal e-d-s hackers could give a clue on how it is supposed to be
used?
