This routine initially checks to see if NULL manager entry point vector, mgr_epv, was passed.

这个例程首先检查传递的管理器入口点向量mgr_epv是否是NULL。

The protocol service is queried using the management entry point vector and the statistics are retrieved for each supported protocol on that system.

使用管理入口点向量查询协议服务，获取系统上支持的每个协议的统计数据。

This routine is used to accomplish the same if one provides the interface handle which is generated by the IDL compiler, a type UUID and manager routine's entry point vector.

这个例程用于完成这个步骤，这需要提供IDL编译器生成的接口句柄、类型UUID和管理器例程的入口点向量。

youdao

it's clear that you want to add a vector that looks like that, because then you go from the start of this to the finish of that, you end up at the same point and you get this invisible 0 vector.

显然应该给它加上这样一个矢量,因为从这个矢量的起点指向那个矢量的终点,最终指向的是同一个点,你就得到这个不可见的零矢量
