Syntax
extern[location]
Where location is optional
Semantics
Provided as additional allocation type information, this tells the compiler NOT to allocate memory for the variable as this has been already done externally. The location argument is optional and just tells the compiler where the variable is to be found (e.g. a C header file) if required.
