Hi,
Fpc sometimes complains (hints) about local variables not being initialized.
My question: how do I initialize more complicated structures like
records? And should I need to (I'm guessing no in the example below, but
the contents of the record will be undefined - no problem as there are
no pointers/strings in there)?
Example:
....
Type
TIfdTag = packed Record
ID: word;
//Tag number
Typ: word;
//Type tag
Count: cardinal;
//tag length
Offset: cardinal;
//Offset / Value
End;
....
Var
tag: TIfdTag;
....
in code somewhere
ReadTag(tag);
As TIfdTag seems to contain non-pointer records only, I thought I could
use Sizeof and tried this:
FillByte(tag, SizeOf(tag), 0); //initialize var.
The compiler warning doesn't go away though.
Is this the recommended way of doing things?
Thanks,

jb
