<a class="link" href="ORBit2-orbit2-allocators.html#CORBA-sequence-set-release" title="CORBA_sequence_set_release()"><code class="function">CORBA_sequence_set_release()</code></a> can be used to set the state of the
release flag. If the flag is set to <a
href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#TRUE--CAPS"
><code class="literal">TRUE</code></a>, the sequence effectively
"owns" the storage pointed to by <em class="structfield"><code>_buffer</code></em>; if
<a
href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#FALSE--CAPS"
><code class="literal">FALSE</code></a>, the programmer is responsible for the storage. If, for
example, a sequence is returned from an operation with its release
flag set to <a
href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#FALSE--CAPS"
><code class="literal">FALSE</code></a>, calling <a class="link" href="ORBit2-orbit2-allocators.html#CORBA-free" title="CORBA_free ()"><code class="function">CORBA_free()</code></a> on the returned sequence
pointer will not deallocate the memory pointed to by
<em class="structfield"><code>_buffer</code></em>.
</p>
<p>
Also, passing a null pointer or a pointer to something other than
a sequence type to either <a class="link" href="ORBit2-orbit2-allocators.html#CORBA-sequence-set-release" title="CORBA_sequence_set_release()"><code class="function">CORBA_sequence_set_release()</code></a> or
<a class="link" href="ORBit2-orbit2-allocators.html#CORBA-sequence-get-release" title="CORBA_sequence_get_release()"><code class="function">CORBA_sequence_get_release()</code></a> produces undefined behavior.

<a class="link" href="ORBit2-orbit2-allocators.html#CORBA-sequence-set-release" title="CORBA_sequence_set_release()"><code class="function">CORBA_sequence_set_release()</code></a> should only be used by the creator of a
sequence. If it is not called for a given sequence instance, then
the default value of the release flag for that instance is <a
