follows:void Closelog (void);It is worth noting that although the use and invocation of this function is very simple, but is necessary, because in the Linux system, the open log is also a resource, if you only use the Openlog function to open the log, and forget to use Closelog to close the log, when the number of open logs accumulated to a certain extent , it causes insufficient memory, which can cause system problems. Therefore, remind the user to pay special attention in the use.Examples of

Developed under Windows, accustomed to the loadstring () function to record text from the resource, so as to achieve multi-language support. But in PHP. and under Linux. Also, not everyone uses loadstring () to load text, but writes its own function, reading text from XML or even from a database. The principle of loading the text resources is nothing more than the Key+value mode, that is, to each string is numbered, and then by number to find the corresponding value. But the problem with this

function return value The return value type must be the same as the return type of the function For the main function, the return value must be of type int. In most systems, the return value of the main function is a status indicator. A return value of 0 indicates that the main function completed successfully, and a non-zero return indicates an error occurred.

In all the previous essays in my series, the software was installed and uninstalled using the Linux distribution's own package management tools (such as apt-get, yum, etc.), and never showed you how to use the source code to build the software yourself. But children's shoes, which have long been in the Unix/linux world, know that compiling and installing software from source code is not so difficult, generally three steps:Configure Make Make InstallThe ability to manage the source code is so s

GNU autotools will be considered as the ideal tool to manage Fortran project after creating a basic program structure by using Eclipse IDE. eclipse IDE is quite convenient for developing a simple project, however, only one target binary can be generated, I. e. A single binary executable or library. therefore, it is still not good enough to manage a large or a collaborated project in which a couple of binaries shoshould be generated with varous types,

What is the startup manager?The startup manager is a program stored in the Start sector of the disk. For example, the hard disk MBR (Master Boot Record). After the system completes the startup test, if the system starts from the MBR, the BiOS (Basic Input/Output System) sends the control to the MBR. The program stored in MBR will run. This program is called the start manager. Its task is to send the control to the operating system to complete the startup process.There are many available start ma

your fear of crumbling in the high place, in response to the Houtie teacher's "do not in the floating sand build high-rise" call. The purpose of learning to assemble now is much different from the previous. As Cs.app said, "the need for programmers to learn to assemble has changed over time, starting with requiring programmers to write programs directly from the Assembly, and now it is required to be able to read and understand the code generated by the optimizer compiler." Can read and underst
