When you define a record or other data type, it’s a common practice also to define a pointer to that type. This makes it easy to manipulate instances of the type without copying large blocks of memory. Standard pointer types exist for many purposes. The most versatile isPointer, which ca...

See Derived Classes, for more information about ambiguity and virtual base classes. C++ allows explicit conversions of pointers to objects or functions to type void *. Pointers to object types can be explicitly converted to pointers to functions if the function pointer type has enough bits to acco...
So far we have talked about types that provide for the declaration of statically allocated variables. A static variable is one that is declared in a program and subsequently denoted by its identifier. It is called static, because it exists (i.e., memory is allocated for it) during the ...
Delphi 指针[2] 指针类型(Pointer types) 可以使用以下语法声明指向任何类型的指针 type pointerTypeName = ^type 定义记录或其他数据类型时,通常也会定义指向该类型的指针。这使得在不复制大内存块的情况下操作该类型的实例变得容易。 标准指针类型有很多用途
Contains basic pointer information common to all pointer types. Applications can retrieve this information using the GetPointerInfo, GetPointerFrameInfo, GetPointerInfoHistory and GetPointerFrameInfoHistory functions.
Pointers in this category include a special kind of pointer known as a null pointer, and any pointer whose memory has been freed. When a pointer is first created, it may be in either a valid or invalid state. However, just like any other variable in IDL, pointers may be redefined at ...
