$resultfalse|int

More Information

The filter hook is applied in the default check_admin_referrer() function after the nonce has been checked for security purposes; this allows a plugin to force WordPress to die for extra security reasons. Note that check_admin_referrer is also a “pluggable” function, meaning that plugins can override it.
