| 679 | | ||3||C4127|| conditional expression is constant||Very common and many believe unhelpful, but a few find it informative, so do not suppress globally. Even while(true) can trigger this! Suppress.|| # pragma warning(disable: 4127) // conditional expression is constant.|| |
| 680 | | |
| 681 | | ||4||C4100|| unreferenced formal parameter||Either surround the parameter with C comments, for example: int */ my_variable */)or just delete if the variable name is uninformative.|||| |
| 682 | | |
| 683 | | 5 C4701 local variable may be used without having been initialized |
| 684 | | |
| 685 | | Best is to recode to avoid the message, but if you are '''very''' sure the message is misleading, suppress. |

| 688 | | |
| 689 | | 6 c4511 copy constructor could not be generated |
| 690 | | |
| 691 | | This can almost certainly be suppressed. |
| 692 | | # pragma warning(disable: 4511) // copy constructor could not be generated |
| 693 | | |
| 694 | | 7 C4180 qualifier applied to function type has no meaning; ignored |
| 695 | | |
| 696 | | This can always be suppressed - but check that you didn't mean to put the const somewhere else. |
| 697 | | |
| 698 | | 8 C4702 unreachable code |
| 699 | | |
| 700 | | Be very cautious about suppressing this, but use of macros may make this troublesome, |
| 701 | | so suppress with care, and always locally. |

| 704 | | |
| 705 | | 9 C4189 local variable is initialized but not referenced |
| 706 | | |
| 707 | | This probably indicates a redundant variable and assignment, so probably remove it. |
| 708 | | |
| 709 | | If you sure it is required (or has negligible cost for some documentation benefit), suppress. |
| 710 | | |
| 711 | | 10 C4224 nonstandard extension used : formal parameter 'arg' was previously defined as a type. |
| 712 | | |
| 713 | | This will bite users who try to compile with Microsoft extensions disabled. |
| 714 | | So is most undesirable, but may be a major nuisance to change the names in code. |
| 715 | | However fixing is the Right Thing, but meanwhile suppressing may be helpful. |
