Re: Scope of specifier extern

Hi,

I've a a question on the specifier extern.

Code example:

void func( void )
{
extern int e;
//...
}

int e = 2;

int main() void
{
func();
return 0;
}

Yes they're the same [at least with GCC on most platforms I can think
of]. "e" will be accessed globally and "int e = 2" exports the symbol
"e".

Now, had you wrote "static int e = 2" they would be different and most
likely platform dependent.
