I. Introduction Generally, the link to the function library is 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 their own doors. Therefore, these function libraries are called static libaray

When writing a C language program, we often encounter many repeated or commonly used parts. If we re-write each time, it is acceptable, but this will greatly reduce the work efficiency, it also affects code readability and is not conducive to code maintenance in the future. We can make them into corresponding function functions. It will be convenient to call them directly during use, and we can also upgrade the functions later. For example, if I want to exchange the values of two variables multi

Understanding of dynamic library and static library, static library 1.1 concept of Database In my opinion, the Library is already written, mature, reusable code. Every program depends on many underlying libraries. It is impossible for everyone to write code from scratch. Therefore, the existence of the

There are two kinds of libraries with Lib suffix, one is static link library (static libary, hereinafter referred to as "still Library"), and the other is the import library (import libary, hereinafter referred to as "import library") of Dynamic Connection library (DLL, here

Function objects and High-Order programming (function objects and higher-order programming) boost. Bind BIND is a generalization of the standard library binder (bind1st and bind2nd. This library supports binding any behavior similar to a function, function pointer, function object, or member function pointer using a unified syntax. It also supports functional composition ). This
