name: duk_pcall_prop
|
|
|
|
proto: |
|
|
duk_int_t duk_pcall_prop(duk_context *ctx, duk_idx_t obj_index, duk_idx_t nargs);
|
|
|
|
stack: |
|
|
[ ... obj! ... key! arg1! ...! argN! ] -> [ ... obj! ... retval! ] (if success, return value == 0)
|
|
[ ... obj! ... key! arg1! ...! argN! ] -> [ ... obj! ... err! ] (if failure, return value != 0)
|
|
|
|
summary: |
|
|
<p>Like <code><a href="#duk_pcall">duk_pcall()</a></code>, but the target function
|
|
is looked up from <code>obj.key</code> and <code>obj</code> is used as the function's
|
|
<code>this</code> binding.</p>
|
|
|
|
example: |
|
|
/* obj.myAdderMethod(2,3) -> 5 */
|
|
duk_idx_t obj_idx;
|
|
duk_int_t rc;
|
|
|
|
duk_push_string(ctx, "myAdderMethod");
|
|
duk_push_int(ctx, 2);
|
|
duk_push_int(ctx, 3);
|
|
rc = duk_pcall_prop(ctx, obj_idx, 2); /* [ ... "myAdderMethod" 2 3 ] -> [ ... 5 ] */
|
|
if (rc == DUK_EXEC_SUCCESS) {
|
|
printf("2+3=%ld\n", (long) duk_get_int(ctx, -1));
|
|
} else {
|
|
printf("error: %s\n", duk_to_string(ctx, -1));
|
|
}
|
|
duk_pop(ctx);
