name: duk_require_callable

|
proto: |
|
|
void duk_require_callable(duk_context *ctx, duk_idx_t index);
|
|
|
|
stack: |
|
|
[ ... val! ... ]
|
|
|
|
summary: |
|
|
<p>Throw an error if the value at <code>index</code> is not callable
|
|
or if the index is invalid.</p>
|
|
|
|
<div class="note">
|
|
There is no "get" primitive (<code>duk_get_callable()</code>) because there's
|
|
no useful C return value for an arbitrary callable value. At the moment this
|
|
call is equivalent to calling <code><a href="#duk_require_function">duk_require_function()</a></code>.
|
|
</div>
|
|
|
|
example: |
|
|
duk_require_callable(ctx, -3);
