While working with SDL, I found that I kept using the same pattern over
and over:
- Get the current clip rectangle.
- Set a new clip rectangle.
- restore the old clip rectangle on scope (exit).
Instead of writing that code again and again, I wrote a simple function
that returns a struct which restores the old clip rectangle in it's
destructor. This works great but now dscanner complains about the
variable being unused.
Is there a way tell dscanner that a variable is intentionally unused?
I don't know about D-Scanner but I know that other similar tools allow
you to prefix the name of a variable with an underscore to indicate that
the variable is intentionally unused.
