[in, out] Destination 指向PVOID 值的指针。 如果 (*Destination) =Comperand,则例程会将 (*Destination) 设置为Exchange。 [in] Exchange 指定要 (*Destination) 设置的 PVOID 值。 [in] Comperand 指定要与 (*Destination) 进行比较的 PVOID 值。 一个小的测试样例 代码语言:cpp 代码运行次数:0 运行 ...

Unlike functions, pointers to functions are objects and thus can be stored in arrays, copied, assigned, passed to other functions as arguments, etc. A pointer to function can be used on the left-hand side of thefunction call operator; this invokes the pointed-to function: ...
which augmentedshared_ptrto allow it to work out of the box for the cases when it owns an array of objects. The current draft of theshared_ptrchanges slated for this TS can be found inN4082. These changes will be accessible via thestd::experimentalnamespace, and included in the<experiment...
We can define pointer of class type, which can be used to point to class objects.class Simple { public: int a; }; int main() { Simple obj; Simple* ptr; // Pointer of class type ptr = &obj; cout << obj.a; cout << ptr->a; // Accessing member with pointer } ...
Pointers to void are used to pass objects of unknown type, which is common in generic interfaces:mallocreturnsvoid*,qsortexpects a user-provided callback that accepts twoconstvoid*arguments.pthread_createexpects a user-provided callback that accepts and returnsvoid*. In all cases, it is the cal...
In this example, we will declare an integer variable and 1) an integer pointer, 2) a pointer to pointer that will store the address the address of first pointer (integer pointer). #include<iostream>usingnamespacestd;intmain(){inta;//normal integer variableint*ptr;//integer pointer declaratio...
