Actually, the way Andrew wrote it, it _is_ needed. It does two things:
- it's the block scope that allows the private variables
- if the "get_user()" fails, the "break" means that you don't have to
have a goto.
<pedantry> The latter is true, but the former can also be done with
just bare braces:
int a=4;
{ int a=3; printf("%d ",a); /* 3 */ }
printf("%d ",a); /* 4 */
</pedantry, only useful to those who wish to write ugly code or source
code parsers>
Not being a person with actual *useful* skills, I can't comment on the
__get_user() issue :-).
