name: duk_del_prop_heapptr
|
|
|
|
proto: |
|
|
duk_bool_t duk_del_prop_heapptr(duk_context *ctx, duk_idx_t obj_idx, void *ptr);
|
|
|
|
stack: |
|
|
[ ... obj! ... ] -> [ ... obj! ... ]
|
|
|
|
summary: |
|
|
<p>Like <code><a href="#duk_del_prop">duk_del_prop()</a></code>, but the
|
|
property name is given as a Duktape heap pointer obtained e.g. using
|
|
<code><a href="#duk_get_heapptr">duk_get_heapptr()</a></code>. If
|
|
<code>ptr</code> is NULL, <code>undefined</code> is used as the key.</p>
|
|
|
|
example: |
|
|
duk_bool_t rc;
|
|
void *ptr;
|
|
|
|
duk_push_string(ctx, "propertyName");
|
|
ptr = duk_get_heapptr(ctx, -1);
|
|
/* String behind 'ptr' must remain reachable! */
|
|
|
|
rc = duk_del_prop_heapptr(ctx, -3, ptr);
|
|
printf("delete obj.propertyName -> rc=%d\n", (int) rc);
