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.
In a statically built program, no dynamic linking occurs: all the bindings have been done at compile time.. Static builds have a very predictable behavior (because they do not rely on the particular version of libraries available on the final system), and are commonly found in forensic and security tools to avoid possible contamination or malfunction due to broken libraries on the examined ...
For example, a binary is dynamically linked against libraries libfoo.so and libbar.so. libfoo defines symbol f and declares it as weak. libbar also defines f and declares it as strong. Depending on the library ordering on the link command line (i.e. -lfoo -lbar ) the dynamic linker uses the weak f from libfoo.so although a strong version is ...
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 ...
Lint is the computer science term for a static code analysis tool used to flag programming errors, bugs, stylistic errors and suspicious constructs. [1] The term originates from a Unix utility that examined C language source code. [2] A program which performs this function is also known as a "linter".
