Being nervous about applying the ! operator to a pointer is needless. It has always been well defined. From the C specification:
"The operand of the ! operator must have arithmetic type or be a pointer, and the result is 1 if the value of its operand compares equal to 0, and 0 otherwise. The type of the result is int."
The concept of Boolean isn't even mentioned here, as it is really just a fiction anyway. Know thy language.
>> By the way, I concur with Thomas Davie: treating a pointer as a Boolean makes me nervous.
