Options to Suppress Messages
You can use several lint options to suppress lint diagnostic messages. Messages can be suppressed with the -erroff option, followed by one or more tags. These mnemonic tags can be displayed with the -errtags=yes option.
The following table lists the options that suppress lint messages.
