|
|
<p>
|
||
|
|
Normalize argument index relative to the bottom of the current frame.
|
||
|
|
The resulting index will be 0 or greater and will be independent of
|
||
|
|
later stack modifications. If the input index is invalid, returns
|
||
|
|
<tt>DUK_INVALID_INDEX</tt>. If you prefer that an error be thrown for
|
||
|
|
an invalid index, use
|
||
|
|
<tt><a href="#duk_require_normalize_index">duk_require_normalize_index()</a></tt>.
