The object file is input for the dynamic linker and can't be statically link edited again. 1<<3: 0000_0000_0000_0000_0000_0000_0000_1000: The object file's undefined references are bound by the dynamic linker when loaded. 1<<4: 0000_0000_0000_0000_0000_0000_0001_0000: The file has its dynamic undefined references prebound. 1<<5
Dynamic loading is a mechanism by which a computer program can, at run time, load a library (or other binary) into memory, retrieve the addresses of functions and variables contained in the library, execute those functions or access those variables, and unload the library from memory.
A shared library or shared object is a computer file that contains executable code designed to be used by multiple computer programs or other libraries at runtime.. When running a program that is configured to use a shared library, the operating system loads the shared library from a file (other than the program's executable file) into memory at load time or runtime.
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).
As the dynamic linker holds modules and resolves dependancies, it populates the IAT slots with actual addresses of the corresponding library functions. Although this adds an extra jump, incurring a performance penalty compared to intermodular calls, it minimizes the number of memory pages that that require copy-on-write changes, thus conserving ...
The open-source implementation of the Java Platform Standard Edition uses libffi to bridge between the interpreter and native code for Zero-Assembly port. Dalvik Dalvik is the virtual machine which runs the Java platform on Android mobile devices. libffi is used on Android ports for which no custom bridging code has been written.
Gopher's hierarchical structure provided a platform for the first large-scale electronic library connections. [4] The Gopher protocol is still in use by enthusiasts, and although it has been almost entirely supplanted by the Web, a small population of actively-maintained servers remains.
