Structures with .DLL's

[Killswitch]

I've downloaded a .dll to help me with generating CD ID's for use with a free service that give's you the name and track listings of CD's that some of you suggested to me in a previous post.

This is the first time i've used a .dll in one of my programs, so I'm a bit shakey to start off with. Now in the documentation this is appended on the end (it's freeware, so I'm not breaking any agreements):

Types
TCdRom = record
HaId : Byte;
Target : Byte;
Lun : Byte;
Vendor : ShortString;
ProductId : ShortString;
Revision : ShortString;
VendorSpec: ShortString;
end;


TCdRoms = record
CdRomCount: Byte;
CdRom : array[0..25] of TCdRom;
end;


TTOC = record
M: Byte;
S: Byte;
F: Byte;
AudioTrack: Boolean; // indicates if the track is an audio or data track
end;


TCdToc = record
TracksOnCD: Byte;
LeadOut : TTOC;
Tracks : array[0..99] of TTOC;
end;

Am I right in saying that these are structures? And if so how do I impliment them properly? Bytes are easy but PB doesn't have a nativge Boolean true/false type does it? And 'Traks : array[0...99] or TTOC is a structured array in a strucuture, how do I impliment that?

Thanks for you help in advance.

Look like structures anyway.

What language was it written in? That would give you an idea how big the boolean is, but IIRC it is normally a long in Windows. You'll also have to watch out for misalignment of data in the structures, since there are a few odd numbered bytes at the start of some.

Structure mystructure
member.type[number_items_in_the_array]
EndStructure

I'm not sure, but I think it was C. Deffinatly not Pascel as there is a Pascel version avliable. Thanks for your help.

This seems to be Delphi.
Boolean = 1 Byte
ShortString = 256 Byte
