Step two: data is copied from the kernel buffer into the user buffer, and the read system call returns. The return from the call caused a context switch from kernel back to user mode.
步骤二：数据从内核空间缓冲区复制到用户空间缓冲区，之后系统调用read返回，这导致了从内核空间向用户空间的上下文切换。
A simple solution for buffer overflows is to switch to a language that prevents them.
针对缓冲区溢出的一种简单解决办法就是转为使用能够防止缓冲区溢出的语言。
That means the IGBT-based switch unit switches from one position to the other depending from the filling status of the buffer and the operation mode of the load.
这意味着，依赖于缓冲器的填充状态和负载的操作模式，基于IGBT的开关单元从一个位置切换到另一位置。
