name: duk_get_boolean
|
|
|
|
proto: |
|
|
duk_bool_t duk_get_boolean(duk_context *ctx, duk_idx_t idx);
|
|
|
|
stack: |
|
|
[ ... val! ... ]
|
|
|
|
summary: |
|
|
<p>Get the boolean value at <code>idx</code> without modifying or coercing
|
|
the value. Returns 1 if the value is <code>true</code>, 0 if the value is
|
|
<code>false</code>, not a boolean, or the index is invalid.</p>
|
|
|
|
<p>Note that the value is not coerced, so even a "truthy" Ecmascript value
|
|
(like a non-empty string) will be treated as false. If you want to coerce
|
|
the value, use <code><a href="#duk_to_boolean">duk_to_boolean()</a></code>.</p>
|
|
|
|
example: |
|
|
if (duk_get_boolean(ctx, -3)) {
|
|
printf("value is true\n");
|
|
}
