C conversion help: Starburn API

[Brian Chirgwin]

Below is some of the C header code for a function I am trying to convert to work in PB. The issue, I believe, is in the DAO_DISC_LAYOUT_ENTRY specifically the __CHAR__TrackName member of the struct. I’ve tried several different ideas but haven't had success. Anyone have any ideas?

Specific questions:

How would one create the DAO_DISC_LAYOUT and ENTRY datatypes?
How would the DECLARE for the DAO_DISC_LAYOUT parameter be passed in the function StarBurn_CdvdBurnerGrabber_DiscAtOnceRawPWFromFileAudioUnicode?

The structure DAO_DISC_LAYOUT contains a dynamic array of entries. How would one do this in PB? Should I just create an area of memory with GLOBALMEM (PB 9 feature) and fill it in the manner required?

Thanks,

Brian

How would one create the DAO_DISC_LAYOUT and ENTRY datatypes?

TYPE DAO_DISC_LAYOUT_ENTRY
   m__LONG__TrackSizeInLBs AS LONG
   m__LONG__TrackStartingLBA AS LONG
   m__BOOLEAN__IsUnicode AS BYTE
   m__CHAR__TrackName AS ASCIIZ * %MAX_PATH * 3
   m__PVOID__File AS DWORD
   m__BOOLEAN__IsDataTrack AS BYTE
   m__BOOLEAN__IsRawTrack AS BYTE
   m__BOOLEAN__IsAudioExTrack AS BYTE
END TYPE

TYPE DAO_DISC_LAYOUT
   m__LONG__NumberOfEntries AS LONG
   m__DAO_DISC_LAYOUT_ENTRY (0 TO %NUMBER_OF_TRACKS - 1) AS DAO_DISC_LAYOUT_ENTRY
END TYPE

Where %NUMBER_OF_TRACKS will be the maximum to be used. There is no problem if there are more than the number specified by m__LONG__NumberOfEntries because the called function will only read m__LONG__NumberOfEntries elements.

How would the DECLARE for the DAO_DISC_LAYOUT parameter be passed in the function StarBurn_CdvdBurnerGrabber_DiscAtOnceRawPWFromFile AudioUnicode?

Declare it as BYREF p__PDAO_DISC_LAYOUT AS DAO_DISC_LAYOUT and pass a variable DIMed as DAO_DISC_LAYOUT.
