Calling a function with incorrect arguments can result in unexpected or unintended program behavior. Conventional functions that are appropriately declared [[DCL07-A. Include the appropriate type information in function declarators]] will fail compilation if they are supplied with the wrong number or types of arguments.
However, there are cases where supplying the incorrect arguments to a function will only generate compiler warnings. These warnings should be resolved [[MSC00-A. Compile cleanly at high warning levels]], but do not prevent program compilation.
