[理工] [OS]-多執行緒的問題
可以請問一下，關於多執行緒在恐龍書上，有幾行沒有很了解他的意思，是否有人可以幫
忙解釋一下，謝謝。
Assuming that the threads are part of the same larger process, the kernel
needs to write the program counter, register set and stack of the outgoing
thread to a backing store, and switch to point to the PCB of the incoming
thread (to look at the new values in the PC, register and stack).
when performing a context switch between processes, we must update additional
information including the code block, the file pointers, the memory.
