Setting the scope of a MACRO

Question

I have a general doubt ..

Is there a way we limit the scope of a MACRO within a .C file just like a static function ?

Answer 1

Macros are done by the pre-processor. The pre-processor reads all files being processed and applies macros and macro logic, the results of which are then passed to the compiler.

Once a macro is defined, its value will be used everywhere the macro is referenced, even in other files.

Please see the GCC Documentation for details regarding macro usage.
