[amibroker] Re: Passing DateTimes to C++ from AFL

["jooleanlogic" <jooleanl@xxxxxxxxxxx>]

Sid the info on the datetime format is in the ADK doco.

It uses an AmiDate union which is 64 bits and contains a PackedDate struct. The doco outlines how the date and time are bit packed.

Also in version 5.28.1, Tomasz released the GetDateTimeArray function for the ADK.
http://www.amibroker.com/devlog/2009/10/21/amibroker-5-29-2-beta-released/
5.28.1 section 7 - GetDateTimeArray.

I haven't used it but from a past post, you need to add the function prototype:
AmiDate* GetDateTimeArray();
to the SiteInterface struct.

I can't see how you'd be able to pass an AmiDate var directly between afl and the dll because the AmiDate is 64 bits and the AmiVar only 32. I have a feeling this might be why the GetDateTimeArray was added to the ADK in the first place but Tomasz will know one way or the other.
The alternative if you can't pass directly is to just pass the date and time seperately as two floats and then construct the AmiDate var yourself if you actually need it in that format.
