NAME

       Builtins::null - Checks if a foreign pointer is NULL

SYNOPSIS

       Bool null( Ptr p )

ARGUMENTS

       p The foreign Ptr to check.

DESCRIPTION

       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.
