icalendar--convert-ical-to-diary

icalendar--convert-ical-to-diary is a compiled Lisp function in `icalendar.el'.

(icalendar--convert-ical-to-diary ICAL-LIST DIARY-FILE &optional DO-NOT-ASK NON-MARKING)

Convert iCalendar data to an Emacs diary file.
Import VEVENTS from the iCalendar object ICAL-LIST and saves them to a
DIARY-FILE. If DO-NOT-ASK is nil the user is asked for each event
whether to actually import it. NON-MARKING determines whether diary
events are created as non-marking.
This function attempts to return t if something goes wrong. In this
case an error string which describes all the errors and problems is
written into the buffer `*icalendar-errors*'.
