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?
There is not enough code shown to say much. If the ReadTag procedure
is declared with a presumably var paramater of type TIfdTag then the
compiler warning is OK if the passed record has not been initialized
in any way. In such case it may/should help to change the 'var'
paramater to an 'out' parameter to explicitly tell the compiler that
there is nothing going into ReadTag but only the other way.
It's enough code, because FillByte (and others) are defined with a "var"
parameter and such the hint (not a warning) won't go away.
It's an old topic already and we have just to live with it (regarding
the Fill* functions). ^^

Sven
