Hi,
Attached patch exposes two new e-cal APIs to fetch events for a given
source from e-d-s.
1) e_cal_get_items_from_source (ESource* source, ESourceType type, const
char* query, GError** error)
This API fetches all the events that satisfies the sexp given in
"query" for the given source of type "type".
If "query" is null, it fetches all available events for the given
source "source".
2) e_cal_get_items_from_source_occur_in_range (ESource* source,
ESourceType type, time_t start_time, time_t end_time, GError** error)
This API queries for all events available for a source between a
specified date-time range.
This internally calls e_cal_get_items_from_source.
Let me know your comments.
Thanks,
V. Varadhan
