现在这一类型的值可以通过内建的函数new来分配，这将返回一个指针，指向一块内存单元，其所占内存槽初始化为零。

Values of this type can now be allocated using the built-in function new, which returns a pointer to the value in memory with all slots initialized to the zero value.

在这个方案中，对象由指针代表，而GtkWidget是GTK +层次结构中的基本类型——叫做类，其他类都从它派生而来。

In this scheme, objects are represented by Pointers, and GtkWidget is the basic type — called a class — in the GTK + hierarchy from which all other classes are derived.

本身支持64位类型的系统通常都采用一种称为“LP64”的模型，其中long类型和指针大小都是64位的。

Systems with native 64-bit types often went to a model called "LP64," where the long and pointer sizes were both 64 bit.
