What I wrote above is not good, it's behaviour is implementation dependent.
The right approach is to check each return value against 0, since they are
pointer values.


So thee above should be:


if(!whatever1[p->first] && !whatever2[p->first] && ... &&
!whatevern[p->first])
{
 //....

}



Sorry but apparently the caffeine had not reached my mind yet.
