name: duk_resize_buffer
|
|
|
|
proto: |
|
|
void *duk_resize_buffer(duk_context *ctx, duk_idx_t index, duk_size_t new_size);
|
|
|
|
stack: |
|
|
[ ... val! ... ]
|
|
|
|
summary: |
|
|
<p>Resize a dynamic buffer at <code>index</code> to <code>new_size</code> bytes.
|
|
If <code>new_size</code> is larger than the current size, newly allocated bytes
|
|
(above old size) are automatically zeroed. Returns a pointer to the new buffer
|
|
data area. If <code>new_size</code> is zero, may return either <code>NULL</code> or some
|
|
non-<code>NULL</code> value. If resizing fails, the value at <code>index</code> is not
|
|
a dynamic buffer, or <code>index</code> is invalid, throws an error.</p>
|

|
|
example: |
|
|
void *ptr;
|
|
|
|
ptr = duk_resize_buffer(ctx, -3, 4096);
