Microsoft Warnings
C4100 - Unreferenced formal parameter
Suggestion
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.
Suppression
# pragma warning(disable: 4100) // 'name' : unreferenced formal parameter
C4127 - Conditional expression is constant
Suggestion
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.
Suppression
# pragma warning(disable: 4127) // conditional expression is constant.
