Warning C26461
The pointer argument 'argument' for function 'function' can be marked as a pointer to
const(con.3).
Remarks
A function with a T* argument has the potential to modify the value of the object. If that isn't the intent of the function, it's better to make the pointer a const T* instead.
Code analysis name: USE_CONST_POINTER_ARGUMENTS
Example
struct MyStruct
{
void MemberFn1() const;
void MemberFn2();
};
void Function1_Helper(const MyStruct* myStruct);
void Function1(MyStruct* myStruct) // C26461, neither of the operations on myStruct would modify the pointer's value.
{
if (!myStruct)
return;
myStruct->MemberFn1(); // The member function is const
Function1_Helper(myStruct); // Function1_Helper takes a const
}
void Function2(MyStruct* myStruct)
{
if (!myStruct)
return;
myStruct->MemberFn2(); // The member function is non-const, so no C26461 will be issued
}
