You could force the caller to pre-create variables
returnedstring = repeat("\00",nSize+1)
Then just pass "returnedstring" as a variable name as the argument.
The plugin will see a string pointer and uses getvaraddr to get
string pointer.

Yes this would work although you would then have to eval expressions
passed as arguments or force variable names only as arguments.
