recur_describe_recurrence_ex

Describes some simple types of recurrences in a human-readable and localized way.

The flags influence the output format and what to do when the icalcomp contains more complicated recurrence, some which the function cannot describe.

The week_start_day is used for weekly recurrences, to start the list of selected days at that day.

If datetime_fmt_func is null, the time_format_date_and_time is used to format data/time value.

Free the returned string with g_free, when no longer needed.

Parameters:

icalcomp	an Component
week_start_day	a day when the week starts
flags	bit-or of RecurDescribeRecurrenceFlags
datetime_fmt_func	formatting function for date/time value

Returns:

a newly allocated string, which describes the recurrence of the icalcomp, or NULL, when the icalcomp doesn't recur or the recurrence is too complicated to describe, also according to given flags.
