This article only analyzes the changes in the user stack and kernel stack after the signal is sent to the user program. Without analyzing real-time signals, the entire process is basically the same. Many references , so some code may be different
The underlying data type is directly allocated in the stack space, and the form parameters of the method are allocated directly in the stack space when the method call is completed and reclaimed from the stack space. The reference data type needs to
