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.
