Details
ECalRecurInstanceFn ()
gboolean (*ECalRecurInstanceFn) (ECalComponent *comp
,time_t instance_start
,time_t instance_end
,gpointer data
);
ECalRecurResolveTimezoneFn ()
icaltimezone * (*ECalRecurResolveTimezoneFn) (const gchar *tzid
,gpointer data
);
e_cal_recur_generate_instances ()
void e_cal_recur_generate_instances (ECalComponent *comp
,time_t start
,time_t end
,ECalRecurInstanceFn cb
,gpointer cb_data
,ECalRecurResolveTimezoneFn tz_cb
,gpointer tz_cb_data
,icaltimezone *default_timezone
);
Calls the given callback function for each occurrence of the event that
intersects the range between the given start
and end
times (the end time is
not included). Note that the occurrences may start before the given start
time.
If the callback routine returns FALSE the occurrence generation stops.
Both start and end can be -1, in which case we start at the events first instance and continue until it ends, or forever if it has no enddate.
The tz_cb is used to resolve references to timezones. It is passed a TZID and should return the icaltimezone* corresponding to that TZID. We need to do this as we access timezones in different ways on the client & server.
The default_timezone argument is used for DTSTART or DTEND properties that are DATE values or do not have a TZID (i.e. floating times).

e_cal_recur_obtain_enddate ()
time_t e_cal_recur_obtain_enddate (struct icalrecurrencetype *ir

,gboolean convert_end_date
);
e_cal_recur_ensure_end_dates ()
gboolean e_cal_recur_ensure_end_dates (ECalComponent *comp
,gboolean refresh
,ECalRecurResolveTimezoneFn tz_cb
,gpointer tz_cb_data
);
This recalculates the end dates for recurrence & exception rules which use
the COUNT property. If refresh
is TRUE
it will recalculate all enddates
for rules which use COUNT. If refresh
is FALSE
, it will only calculate
the enddate if it hasn't already been set. It returns TRUE
if the component
was changed, i.e. if the component should be saved at some point.
We store the enddate in the "X-EVOLUTION-ENDDATE" parameter of the RRULE
or EXRULE.

e_cal_get_recur_nth ()
const gchar ** e_cal_get_recur_nth (void
);
Returns an array of 31 translated strings for each day of the month (i.e. "1st", "2nd", and so on).
Returns : |
a pointer to an array of strings. This array is static, do not free it. |
