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。

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.

这个简单的例程释放运行时分配给接口id向量结构的内存。

This is a simple procedure to free up the memory allocated by the runtime to the interface ID vector structure.
