In some projects, considering the security and stability of the system, some DLL or lib libraries are often encapsulated for use by others. How can we create DLL or lib files? Let's explain the basic production methods based on your actual situation.The following are my personal operation records:1. How to compile dynamic library dll:Create a Dynamic Link Library:

Using the PHP Curl Library, you can easily and effectively grab pages. You just need to run a script, then analyze the page you crawled, and then you can get the data you want in a program. Whether you want to take part of the data from a link, or take an XML file and import it into the dat

Although composer allows us to reuse many existing class libraries (for example, packagist.org), we may still use packages or class libraries that are incompatible with composer. Also in a project, we may create a class of libraries, and may not be prepared to become the composer package. At this time we can use our own unique class

Previously said, if the amount of data to be stored in a database is relatively small, but one table stores more data, such as log table, it is necessary to consider the table storage; But what if the overall storage capacity of a database is relatively large? At this point, we need to consider the library, is to build multiple databases to save data. Here, for example, even if the survey is not many, but the number of people involved in the survey is

In easy language, you can use the "Easy-to-write (exek)" function to develop easy-to-language support libraries. Not only are there no functional limitations, but you can also play with the "Flowers, even the "Flowers" that others cannot play.
I. Do not use command Classification
Commands in the supported libraries are generally divided into several categories. For example, commands in the core library of easy language are divided into "process
I. IntroductionFor more information, seeOn Compiling and linking gcc/g ++ in UNIX systems.
Generally, the links to the function library are completed during the compilation period (compile time. All related object files and libraries are linked to form an executable file ). When the program is running, it has nothing to do with the function library, because all the required functions have been copied to the

[Static connection and dynamic link library]
[Static link]---> Static library: Link to the source program and load it to the virtual memory[Dynamic Link]---> Shared Library:For each database, the operating system allocates a specific virtual memory address.
Both static and dynamic libraries share code. Static link library (LIB ):Complete all assembly work before the program execution and generate an executable target file (exe file ). Static databases have two features:
The executable file generated after the Link contains the code of all functions to be called, so it occupies a large disk space.

Although C + + is still the most widely used programming language in the world, it is still becoming more powerful and easy to use. Do you believe me? Let me slow down.The current version of standard C + + was finalized in 1998, providing strong support for traditional procedural programming (procedural programming) and object-oriented and generic programming (generic programming). Just as the old (1998) C + + was a s
