C uses the term "identifier" where this article uses "name" (the latter of which is what C++ uses to formalize linkage): An identifier declared in different scopes or in the same scope more than once can be made to refer to the same object or function by a process called linkage. [1] The following is a common example of linkage:
Any static library function can call a function or procedure in another static library. The linker and loader handle this the same way as for kinds of other object files. Static library files may be linked at run time by a linking loader (e.g., the X11 module loader). However, whether such a process can be called static linking is controversial.

Transcription and transposition errors may also occur in syntax when computer programming or programming, within variable declarations or coding parameters. This should be checked by proofreading; some syntax errors may also be picked up by the program the author is using to write the code.
Static linking is the result of the linker copying all library routines used in the program into the executable image. This may require more disk space and memory than dynamic linking, but is more portable, since it does not require the presence of the library on the system where it runs. Static linking also prevents "DLL hell", since each ...
Translation units define a scope, roughly file scope, and functioning similarly to module scope; in C terminology this is referred to as internal linkage, which is one of the two forms of linkage in C. Names (functions and variables) declared outside of a function block may be visible either only within a given translation unit, in which case they are said to have internal linkage – they are ...
The procedure call uses an indirect pointer pair [11] with a flag to cause a trap on the first call so that the dynamic linkage mechanism can add the new procedure and its linkage segment to the Known Segment Table (KST), construct a new linkage segment, put their segment numbers in the caller's linkage section and reset the flag in the ...
Dynamic linking offers three advantages: Often-used libraries (for example the standard system library) need to be stored in only one location, not duplicated in every single binary. If a library is upgraded or replaced, all programs using it dynamically will immediately benefit from the corrections. Static builds would have to be re-linked first.
