The Windows operating system contains compiled versions of these libraries known as dynamically-linked libraries (), which are executable libraries that can be used by multiple programs while only one copy of the library is loaded into memory.
A dynamic-link library (DLL) is a shared library in the Microsoft Windows or OS/2 operating system. A DLL can contain executable code (functions), data , and resources . A DLL file often has file extension .dll even though this is not required.
Dynamic-link library, or DLL, is Microsoft's implementation of the shared library concept in the Microsoft Windows and OS/2 operating systems.These libraries usually have the file extension DLL, OCX (for libraries containing ActiveX controls), or DRV (for legacy system drivers).
windows.h is a source code header file that Microsoft provides for the development of programs that access the Windows API (WinAPI) via C language syntax. It declares the WinAPI functions, associated data types and common macros. Access to WinAPI can be enabled for a C or C++ program by including it into a source file: #include <windows.h>
Dynamic linking or late binding is linking performed while a program is being loaded or executed , rather than when the executable file is created. A dynamically linked library (dynamic-link library, or DLL, under Windows and OS/2; shareable image under OpenVMS; [7] dynamic shared object, or DSO, under Unix-like systems) is a library intended ...
The Portable Executable (PE) format is a file format for executables, object code, dynamic-link-libraries (DLLs), and binary files used on 32-bit and 64-bit Windows operating systems, as well as in UEFI environments. [2]
Examples of file formats use for both dynamic library and executable files include ELF, Mach-O, and PE. A dynamic library is called by different names in different contexts. In Windows and OS/2 the technology is called dynamic-link library. In Unix-like user space, it's called dynamic shared object (DSO), or usually just shared object (SO).
Often, a Windows dynamic-link library (DLL) has the file extension .dll, [20] although sometimes different extensions are used to indicate general content, e.g. .ocx for a OLE library. A .lib file can be either a static library or contain the information needed to build an application that consumes the associated DLL. In the latter case, the ...
