The same architectural concept that allowed GDI to load different device drivers is that which allowed the Windows shell to load different Windows programs, and for these programs to invoke API Retrieved 2009-07-11. ^ MSDN, Using extern to Specify Linkage ^ https://msdn.microsoft.com/en-us/library/ms680573.aspx ^ DLL Spoofing in Windows ^ DLL Preloading Attacks ^ More information about the DLL Preloading remote attack vector ^ Dll Group
These functions are analogous to dlopen, dlsym, and dlclose in the POSIX standard API. Now if this executable is run, bits of the executable are missing (i.e the stubs) so the loader goes through the executable fixing up the missing stubs. As an example, if several parts of a program need to perform the same action that action may be placed into a .DLL file (library) that the various program parts can http://sammcallister.com/dll-file/dll-extension.html However an application may be linked against an import library to allow delayed loading of the dynamic library. In this case the operating system will not try to find or load

ICL files are icon libraries while FONT and FOT files are font files. If the application does not handle the exception, it will be caught by the operating system, which will terminate the program with an error message.
