Dynamic loading and dynamic linking in os
WebDynamic linking consists of compiling and linking code into a form that is loadable by programs at run time as well as link time. The ability to load them at run time is what distinguishes them from ordinary object files. Various operating systems have different names for such loadable code: UNIX: Sharable Libraries. WebAug 2, 2024 · Implicit linking, where the operating system loads the DLL at the same time as the executable that uses it. The client executable calls the exported functions of the DLL the same way as if the functions were statically linked and contained within the executable. Implicit linking is sometimes referred to as static load or load-time dynamic linking.
