Well I would certainly go for the unsigned 8 bit array parameter
method. That is the best one and contrary to your claim does not
require any changes to the DLL. For the rest it is a good
recommendation and the most direct approach to do, what the OP has to
do.

I am having difficulties using a DLL with is returning a string will
nulls in the middle of it. I would be interested in seeing your
example of using lstrcpyn from kernel32.dll or any other examples that
you may have?

For which platform and API? The types LabVIEW shows are the fundamental
C types each C compiler should understand properly and means the same

WinAPI uses a number of types which are sometimes identical but the
mostly used type which would correspond with unsigned char would be
BYTE and UCHAR.
