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?
Another way would be to have the RAII wrapper in a with
statement, but it produces extra indentation, which you might not
like:
with (MyStruct(100, 200)) {
// code that uses the new clip rectangle
}
