OK, that certainly works.
But is this the only way to do it?
What if I have a lot of code which returns a struct (or vector,
etc..) by creating an intermediate variable in the function; and I do
not want to modify all the occurrences of the function in the code,
only the function itself.
Can I eliminate the creation of the extra variable, while returning
the struct (but not as a parameter) ?
Also, thanks for the quick reply.
