6 Builtins::null - Checks if a foreign pointer is NULL
7
9 Bool null( Ptr p )
10
12 p The foreign Ptr to check.
13
15 Returns true if the foreign pointer is NULL. This is useful in testing
16 whether a foreign function returns something valid, before throwing an
17 exception. This is the only way, in general, that Ptr should be queried
18 in Kaya; usually it is better to manipulate pointers C side.
