Global and Static

[hyderabadblues]

I have a doubt regarding how to access global variables if already
there is one static variable with the same name defined at the
beginning of file outside any function.

E.g:
//File client.c
int iGlobalVar; // Global Variable

// main.c

static int iGlobalVar;

int main()
{
// How to access iGlobalVar here;
}

In main.c, rename `iGlobalVar` to `someDecentName`.

PS there should be a `client.h` header file containing the extern
declaration for `iGlobalVar`, which you #include into `client.c`
and `main.c`.

PPS I hope `iGlobalVar` has a decent name too.

I typed an answer and then deleted it thinking that this *must* be
homework. If it is not, the *real* answer is "don't do this" -- at
the very least you are creating a mystery for others reading the code
later.
