据我所知，linux/unix 上的大多数系统调用在收到信号时都会中断。根据下面的博文，有一些系统调用没有被中断:
In general function that return immediately (don't wait for any I/O operation to complete or sleep) are not interruptible like socket(2) which just allocates a socket and doesn't wait for anything.

是否有这些函数的列表？任何与此主题相关的链接都会有所帮助。
最佳答案
What is the mechanism that kernel uses to decide which call is interruptible and which one is not? (if the story with "socket()" is true)
任务有位掩码，可以用set_task_state设置到 TASK_INTERRUPTIBLE 和 TASK_UNINTERRUPTIBLE(定义 here)。
Is there a list of those kind of functions?
我不认为存在不间断函数列表。您可以搜索 TASK_UNINTERRUPTIBLE 的用法(例如 this)
编辑:example用 signal_pending_state 检查这个标志
