Syntax
const jsid JSID_VOID; const JS::HandleId JSID_VOIDHANDLE; // Added in SpiderMonkey 31
Description
JSID_VOID
does not occur in JS scripts but may be used to indicate the absence of a valid jsid
. A void jsid
is not a valid id and only arises as an exceptional API return value, such as in JS_NextProperty
. Embeddings must not pass JSID_VOID
into JSAPI entry points expecting a jsid and do not need to handle JSID_VOID
in hooks receiving a jsid except when explicitly noted in the API contract.
JSID_VOIDHANDLE
is the handle to the jsid
which value is JSID_VOID
.
