Top 10 points for writing C Programs
To write a C Language Program, the most important thing is to clearly analyze the problems to be solved, design a solution to the problem, and implement the process of solving the problem through computation, perform a scientific and structured decomposition of the problem solving process. The following suggestions may be helpful when we further consider how to write a program.
Some of these suggestions are genera
1. Process Information
1 PS
[Root @ test/root] # ps-Aux
Parameter description:
A: select to list all programs.
U: list all user programs
X: list all tty programs
Example:

UNIX link Processing
We already know that the link actually refers to the process of linking the symbol referenced in one module with its definition in another module. We also know that links are divided into dynamic links and static links. Either way. The linked program searches for every module in the program, including every library file used, to find definitions of external symbols that are not defined in a module. If no de
defined to execute external programs. In this thread's run function, I call the fork and execv functions to execute external programs, redirects the standard output of the executable program to the pipeline, reads the information from the pipeline, and then transmits the information back to the main thread using the qapplication: postevent () function, the main thread append the information to the text box
, you can use gimp, which is almost the same as Photoshop.
Automatic Management Tool: Make. I can use make to automatically compile programs, automatically compile documents, and automatically update illustrations ...... It is fully automated and does not repeat work.
Numerical Calculation Program: SCILAB. This program can basically replace Matlab.
Algebraic computing program: Maxima. This program is based on one of the world's oldest computer algebra
Zabbix In addition to its own template provides monitoring CPU, disk capacity, memory, such as the "Old three" function, but also can choose to monitor the server designated programs, in general, the company will have their own developers in Java or C + + write some programs on their respective servers run, and Zabbix can implement "monitoring these programs and
Advanced ASP programming (3): Accessing script programs
With the enhanced knowledge of form in the previous HTML, is it possible to start the ASP journey? Not necessarily.Programmers who have systematically studied ASP will understand that it is always crucial to learn the scripting language before the system learns the embedded objects and components of ASP.Why? Why should we learn the scripting language? What is the relationship between ASP and scri
Nowadays, with the popularity of the network, server programs are widely used. How can we use Delphi to design strong servers?Some people say that if you want to design a server, you must use VC to design it. In fact, this person makes some sense, because if you want to design a server using Delphi, if you want to design an efficient server, do not use most of the controls that Delphi brings (it is best not to use the Delphi control). Why? I will tell

I found that some students often spend a long time learning how to use a compilation tool when learning a language.RealIt's quite confusing.. There are not only many compilation tools, but also continuous elimination. We know that the C compilation tools are (turboc, Vc, Vim, ADS .......) if we spend a lot of time mastering them, it would be a great tragedy. It is vital that we spend a lot of time learning a language. I hope you only have a rough understa

I am working on a plug-in recently.ProgramTo obtain data from other programs from the serial port, but the problem is that the serial port is exclusively used, that is, only one program can read or send data to the serial port.
So how can I obtain the same serial port data from other programs without shutting down other programs?
