What is Linkage?
Linkage determines whether a name, like a variable or function, refers to the same entity when it appears in multiple files. External linkage means the name is visible and shared across files, internal linkage restricts it to the file it is defined in, and no linkage applies to names like local variables that exist only within a block. Linkage is controlled with the static and extern keywords at file scope.
