警告 C26461
函数“function”的指针参数“argument”可标记为指向
const
的指针 (con.3)。
备注
具有 T*
参数的函数有可能修改对象的值。 如果这不是该函数的意图,最好将指针改为 const T*
。
代码分析名称:USE_CONST_POINTER_ARGUMENTS
示例
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
}
