In pascal terms this is a single dimensional array aka vector of
PChar.
Do I have to make copies of any string or is it sufficient to fill
up an
array with PChar?
That completely depends on what the Pascal and C programs do with
those pchars afterwards. In general, there's no difference in passing
an array of pchars to a C function compared to passing them to a
Pascal procedure: just make sure they are not freed before their last
use. Only if the C program may free them later, you have to allocate
them using malloc/free (although that's unlikely to be the case).
