As far as I know, The Delphi variant is used also to copy dynamic arrays, possibly also variant arrays. The above function is a dummy declaration, as found in the documentation - because in reality it is handled by internal system functions (you can search for _copy, _copyvar _objCopy etc. in the system unit of delphi). However, for strings, the behaviour should be the same. For dynamic arrays, I don't think FPC has a similar function.
