Builtins.null(3kaya)
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.
