proto: |
|
|
duk_idx_t duk_normalize_index(duk_context *ctx, duk_idx_t index);
|
|
|
|
stack: |
|
|
[ ... val! ... ]
|
|
|
|
summary: |
|
|
<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
|
|
<code>DUK_INVALID_INDEX</code>. If you prefer that an error be thrown for
|
|
an invalid index, use
|
|
<code><a href="#duk_require_normalize_index">duk_require_normalize_index()</a></code>.</p>
|
|
|
|
example: |
|
|
duk_idx_t idx = duk_normalize_index(ctx, -3);
