I actually think this is a good example of the exception-rule. The
function wants to take true or false in "int", and the caller has a
pointer. And !!ptr is a shorter and more established way than ptr
!= NULL to turn non-NULL ness into an int boolean, without having to
either repeat or introducing an otherwise unnecessary temporary.
Though !!ptr might might be a shorter way to turn a pointer into an
int boolean I think the documentation says pretty well why we
shouldn't be using it,
".. can be extremely confusing to others".
Should I drop this treating is an exception rule (or) should I keep this
back?
Thanks,
Kaartic
