Off the wall question on VARs

[Technocrat]

Ok this is a strange question that CyberCartsen and I have been discussing and we have not figured it out. I was wonder if some one else knew this. Or if anyone else even does these types of VARs.

Its about VARs that are not local, and not really global. Example:

a .h file

...
extern int GlobalVar;

void whateverfunction();
... 

a .cpp file

...
int GlobalVar;
int notreallyGlobal;  //This is VAR at hand

void whateverfunction()
{
  int LocalVar;
}
... 

Ok now GlobalVar is of course a Global VAR through out your program. LocalVar is of course a Local VAR in that function. So what is notreallyGlobal called since it is only Global in that cpp? Is it still called Global?

It's still a global, but you can only access it if you have a definition -- for example using extern.

[Technocrat]

Right but I only wanted that VAR to accessed by the functions in this cpp, thats why I did not extern it.

[parksie]

Since by default they're only file-global if defined at file scope (not inside a function or namespace), just call it global

[Technocrat]

Thats the conclusion I came to, I just thought there might be another name for it like, Locally Global, or something

[parksie]

Well, I've never heard them called anything different, so I don't know if there's a real name for them...although if you called them File Global people would probably know what you meant.

Hmm...Yeah I like that. That should work fine.

Thanks.
