[Dev-C++] What is a static function

[<vil...@ya...>]

> I don't

> > if (!inittedBV)
> >     {
> >     int i;
> >     for (i=0; i<ArraySize(bV); i++)
> >     bV[i] = -1;
> >     bV['a'] = bV['A'] = A_B_V;
> >     bV['b'] = bV['B'] = B_B_V;
> >     bV['c'] = bV['C'] = C_B_V;
> >     bV['d'] = bV['D'] = D_B_V;
> >     bV['e'] = bV['E'] = E_B_V;
> >     inittedBV = TRUE;
> >     }
