ctypes exports the byref() function which is used to pass parameters by reference. The same effect can be achieved with the pointer() function, although pointer() does a lot more work since it constructs a real pointer object, so it is faster to use byref() if you don’t need the poi...
Actual parametersare the values that are passed to a function when it iscalled. They are also known asarguments. These values can beconstants,variables,expressions, or even other function calls. When a function is called, the actual parameters are evaluated, and their values are copied into the...

Parameter modifiers enable pass-by-reference semantics, with distinctions for read-only, and `out` parameters. The `params` modifier allows optional arguments.

除非你指定其他方式,函数参数会用实际参数值的拷贝进行初始化,函数调用者会获得函数返回值的一份拷贝。这些拷贝由对象的拷贝构造函数生成。这使得按值传递(pass-by-value)变成一项昂贵的操作。举个例子,考虑下面的类继承体系(Item 7): 1classPerson {23public:45Person();//parameters omitted for simplicity67...
The major difference between call by value and call by reference in C is that in call by value a copy of actual arguments/parameters is passed to respective formal arguments/parameters, while in call by reference the location (address) of actual argument
Call by Reference in the C Programming Language In call by reference, the address of arguments that are passed onto the function is copied into the formal parameters. Recall that the argument is the list of parameters we use while calling the function. The formal parameters are the parameter ...
