| | 5 | == C4100 - Unreferenced formal parameter == #c4100 |
| | 6 | |
| | 7 | Suggestion:: |
| | 8 | Either surround the parameter with C comments, for example: `int /* my_variable */`) or just delete if the variable name is uninformative. If in other's module(s), or you are too busy/idle, at least suppress warning. In generic code you might not be able to comment the variable name as it might actually be used to call a static function. In this case simply referencing the variable (varname;) in the function body eliminates the warning. |
| | 9 | Suppression:: |
| | 10 | `# pragma warning(disable: 4100) // 'name' : unreferenced formal parameter` |
| | 11 | |
| | 12 | == C4127 - Conditional expression is constant == #c4127 |
| | 13 | |
| | 14 | Suggestion:: |
| | 15 | Very common and many believe unhelpful, but a few find it informative, so do not suppress globally. Even `while(true)` can trigger this! `while(true)` can be rewritten as `for(;;)` eliminating the warning. |
| | 16 | Suppression:: |
| | 17 | `# pragma warning(disable: 4127) // conditional expression is constant.` |
