name: duk_opt_uint
|
|
|
|
proto: |
|
|
duk_uint_t duk_opt_uint(duk_context *ctx, duk_idx_t idx, duk_uint_t def_value);
|
|
|
|
stack: |
|
|
[ ... val! ... ]
|
|
|
|
summary: |
|
|
<p>Get the number at <code>idx</code> and convert it to a C <code>duk_uint_t</code>
|
|
by first clamping the value between [0, DUK_UINT_MAX] and then
|
|
truncating towards zero. The value on the stack is not modified.
|
|
If the value is <code>undefined</code> or the index is invalid,
|
|
<code>def_value</code> default value is returned. In other cases
|
|
(<code>null</code> or non-matching type) throws an error.</p>
|
|
|
|
example: |
|
|
unsigned int count = (unsigned int) duk_opt_uint(ctx, 1, 3); /* default: 3 */
