Hi List,
I found that there are some weird looking instances in kernel where a
function has been DEFINED (as opposite to DECLARED) using and "extern"
keyword. For e.g., the following code in arch/alpha/include/asm/io.h:
extern inline void __iomem *generic_ioportmap(unsigned long a)
{
return alpha_mv.mv_ioportmap(a);
}
Using a definition along with extern does not make any sense to me.
Can some one please enlighten what is its use / purpose?
Thanks,
Rajat Jain
