Controls the recognition of unreferenced variables.

This pragma is compatible with the following platform targets:

If the pragma warn_unusedvar is on, the compiler generates a warning when it encounters a variable you declare but do not use.

This pragma corresponds to the Unused Variables option in the C/C++ Warnings settings panel. To check whether this option is on, use __option (warn_unusedvar), described in "Checking Options." For more information about this warning see "Finding Unused Variables."
