Symbian - Where I can find specification of the calendar file?

I want to write an application for syncing symbian ca开发者_JAVA技巧lendar with my own software, where I can find specification for the file where Symbian writes all entries to the calendar ?

Since interoperability is key here, why not use Symbian's support of the vCal standard?

See the documentation of the CCalDataExchange class in the developer library.

You might also want to check out the current work being done to support the newer CalDAV standard.

Shameless relevant plug: Quick Recipes On Symbian OS contains a whole chapter about interfacing with the Symbian OS C++ Calendar API.

What you need is the API to the Symbian calendar. Although there is a calendar database as an actual file, it is unlikely that you will be able to access this file directly.

You can find the documentation at Using Calendar (CalInterimAPI). You can also look at Calendar Interim API Example v1.1.
