Checks if a foreign pointer is null
Usage
Bool null( Ptr p )
Arguments
p The foreign Ptr to check.
Overview
Returns true if the foreign pointer is NULL. This is useful in testing whether a foreign function returns something valid, before throwing an exception. This is the only way, in general, that Ptr should be queried in Kaya; usually it is better to manipulate pointers C side.
