Also in this table are a couple of simplification functions that encapsulate the kernel functions in table 2 (requiring a single call instead of multiple calls).

表2中还有一些简化函数，它们封装了的几个内核函数(用一个调用代替多个调用)。

You can also override regular functions in a subclass and call the overridden parent function from within the subclass.

您也可以在子类中重写规则函数，从子类中调用重写的父类函数。

You can also declare functions that probes can call, which is perfect for common functions for which you'd like to serve multiple probes.

您还可以声明探针可以调用的函数，尤其是希望供多个探针调用的通用函数。
