The ordinal represents the position of the function's address pointer in the DLL Export Address table. DLLs are so much like an EXE that the file format itself is the same.

For example, in Windows operating systems, the Comdlg32 DLL performs common dialog box related functions. They are similar to .so files in Linux/Unix. Hence the name Dynamic Link Library, parts of the linking process is being done dynamically at run time by the executable loader.

Features of DLL[edit] Since DLLs are essentially the same as EXEs, the choice of which to produce as part of the linking process is for clarity, since it is possible to Internal functions are typically intended to be called only from within the DLL where they are defined. DLLs provide a mechanism for shared code and data, allowing a developer of shared code/data to upgrade functionality without requiring applications to be re-linked or re-compiled.

While the DLL code may be shared, the data is private except where shared data is explicitly requested by the library. Dynamic Link Library Download Delphi does not need LIB files to import functions from DLLs; to link to a DLL, the external keyword is used in the function declaration to signal the DLL name, followed Why can't linear bounded automata accept an empty string?

DLLs provide a way to modularize applications so that their functionality can be updated and reused more easily.

Each module can be loaded into the main program at run time if that module is installed. With dynamic linking, shared code is placed into a single, separate file. It is not possible to directly execute a DLL, since it requires an EXE for the operating system to load it through an entry point, hence the existence of utilities like Secure containers by anticipating and addressing potential risks Incorporate lessons learned from hypervisor virtualization and effectively navigate common concerns, such as user access controls...

Boost C++ Libraries ...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards Click here to view If the DLL cannot be found or loaded, or the called function does not exist, the application will generate an exception, which may be caught and handled appropriately.

For dynamic linking of libraries in general, see Dynamic linker. Such extensions, or plugins, are usually implemented using Dynamic Library Modules (DLL,SO/DSO) loaded at runtime. These DLLs are circuits that provide zero propagation delay, low-clock skew between output clock signals throughout a device, and advanced clock domain control.
