Typo: with -&gt; within. 

I guess *within* would be better.

 ## External vs. internal linkage
 
-A *free function* is a function that is defined at global or namespace scope. Non-const global variables and free functions by default have *external linkage*; they are visible from any translation unit in the program. Therefore, no other global object can have that name. A symbol with *internal linkage* or *no linkage* is visible only within the translation unit in which it is declared. When a name has internal linkage, the same name may exist in another translation unit. Variables declared with class definitions or function bodies have no linkage.

 You can force a global name to have internal linkage by explicitly declaring it as **static**. This limits its visibility to the same translation unit in which it is declared. In this context, **static** means something different than when applied to local variables.
