Long time no update blog, write an article in addition to weeding. This article focuses on a simple example of
A signal is a specific identifier; a slot is a function, unlike a normal function, a slot function can be either associated with a signal or called directly as a normal function.
When an event occurs, by sending a signal, you can activate the slot
Introduction to FunctionsInclude header file function: The Sigaction function is used to change the behavior of a process after receiving a specific signal. Prototype:
int sigaction (int signum,const struct sigaction *act, struct sigaction);

1. How to view the signal: man 7 signal. You can use this command to view all the information.
2. view the signal kill-l
Note that the following 32 signals represent
Prior to designing the board, I had only heard the relevant concepts, but did not really study si related knowledge. Organize some of the previously seen information as follows:(1) Signal Integrity analysisFactors related to SI : reflection,

Use the Sigaction function:The signal function is simple to use, but is not a POSIX standard, and is not implemented on all types of UNIX platforms, so its use is subject toto a certain limit. The POSIX standard-defined signal processing interface

The system we operate in production requires an elegant exit, that is, after the program receives the exit notification, there is a chance to execute a cleanup code
This article comes from A deeper look at signals and Slots,scott Collins 2005.12.19. What we are saying here is that the "signal slot" is not just a signal slot inside the Qt library, but rather a global height that understands the signal slot from
Signals and slots are an important part of QT programming. This mechanism can associate the actions of objects without mutual understanding. In the previous routines, We have connected the signal and slot, declared the signal and slot of the control,
What are the LTE downlink reference signals and upstream reference signals?In R9, the downlink defines four reference signals, respectively, for the cell-specific reference signal (C-RS), the user-specific reference signal (UE-RS, also known as
First, kill, raise, KILLPG function
int Kill (pid_t pid, int sig);
int raise (int sig);
int killpg (int pgrp, int sig);
The KILL command is implemented by calling the Kill function, which can send a specified signal to a specified process or
http://blog.csdn.net/muge0913/article/details/7331129To process a signal, you need to give the processing function called by the system when this signal occurs. The corresponding processing function can be registered for a specific signal (except

I. Common signals:
1. sighup: end signal sent from the terminal
2. SIGINT: the interrupt signal from the keyboard, CTRL + c
3. sigkill: the signal will end the process of receiving the signal.
4. sigterm: signal sent by the kill command

Interruption is the system's response to asynchronous events. During code execution, the process can be interrupted at any time and then run the exception handling program;
