=summary
|
|
<p>Like <code><a href="#duk_realloc_raw">duk_realloc_raw()</a></code> but may
|
|
trigger a garbage collection to satisfy the request. However, the
|
|
allocated memory itself is not automatically garbage collected.
|
|
If allocated size is extended from previous allocation, the newly allocated
|
|
bytes are not automatically zeroed and may contain arbitrary garbage.</p>
|
|
|
|
<p>Memory reallocated with <code>duk_realloc()</code> can be freed with either
|
|
<code><a href="#duk_free">duk_free()</a></code> or
|
|
<code><a href="#duk_free_raw">duk_free_raw()</a></code>.</p>
