| bugprone-macro-parentheses |
| ========================== |
| |
| |
| Finds macros that can have unexpected behaviour due to missing parentheses. |
| |
| Macros are expanded by the preprocessor as-is. As a result, there can be |
| unexpected behaviour; operators may be evaluated in unexpected order and |
| unary operators may become binary operators, etc. |
| |
| When the replacement list has an expression, it is recommended to surround |
| it with parentheses. This ensures that the macro result is evaluated |
| completely before it is used. |
| |
| It is also recommended to surround macro arguments in the replacement list |
| with parentheses. This ensures that the argument value is calculated |
| properly. |
