Dynamic-Link Libraries

Dynamic-link libraries (DLL) are modules that contain functions and data.
A DLL is loaded at run time by its calling modules (.exe or .dll).
When a DLL is loaded, it is mapped into the address space of the calling
process.


DLLs can define two kinds of functions: exported and internal. The
exported functions can be called by other modules. Internal functions
can only be called from within the DLL where they are defined. Although
DLLs can export data, its data is usually only used by its
functions.


DLLs provide a way to modularize applications so that functionality can be
updated and reused more easily. They also help reduce
memory overhead when several applications use the same functionality at
the same time, because although each application gets its
own copy of the data, they can share the code.

Static linking, conversely, occurs at compile time.
