 707 <p><a class="reference internal" href="#c.memcached_cas" title="memcached_cas"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_cas()</span></code></a> overwrites data in the server as long as the “cas”
 708 value is still the same in the server. You can get the cas value of a result
 709 by calling <a class="reference internal" href="memcached_result_st.html#c.memcached_result_cas" title="memcached_result_cas"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_result_cas()</span></code></a> on a memcached_result_st(3)
 710 structure. At the point that this note was written cas is still buggy in memached. Turning on tests for it in libmemcached(3) is optional. Please see
 711 <a class="reference internal" href="memcached_set.html#c.memcached_set" title="memcached_set"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_set()</span></code></a> for information on how to do this.</p>
 712 <p><a class="reference internal" href="#c.memcached_cas_by_key" title="memcached_cas_by_key"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_cas_by_key()</span></code></a> method behaves in a similar method as the non
 713 key methods. The difference is that it uses the group_key parameter
 714 to map objects to particular servers.</p>
 715 <p><a class="reference internal" href="#c.memcached_cas" title="memcached_cas"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_cas()</span></code></a> is testsed with the <a class="reference internal" href="memcached_behavior.html#c.MEMCACHED_BEHAVIOR_USE_UDP" title="MEMCACHED_BEHAVIOR_USE_UDP"><code class="xref c c-type docutils literal notranslate"><span class="pre">MEMCACHED_BEHAVIOR_USE_UDP</span></code></a> behavior enabled. However, when using these operations with this behavior
 716 on, there are limits to the size of the payload being sent to the server.  The
 717 reason for these limits is that the Memcached Server does not allow
 718 multi-datagram requests and the current server implementation sets a datagram
 719 size to 1400 bytes. Due to protocol overhead, the actual limit of the user
 720 supplied data is less than 1400 bytes and depends on the protocol in use as,
 721 well as the operation being executed. When running with the binary protocol,
 722 <a class="reference internal" href="memcached_behavior.html#c.MEMCACHED_BEHAVIOR_BINARY_PROTOCOL" title="MEMCACHED_BEHAVIOR_BINARY_PROTOCOL"><code class="xref c c-type docutils literal notranslate"><span class="pre">MEMCACHED_BEHAVIOR_BINARY_PROTOCOL</span></code></a>, the size of the key,value,
 723 flags and expiry combined may not exceed 1368 bytes. When running with the
 724 ASCII protocol, the exact limit fluctuates depending on which function is
 725 being executed and whether the function is a cas operation or not. For
 726 non-cas ASCII set operations, there are at least 1335 bytes available to
 727 split among the key, key_prefix, and value; for cas ASCII operations there
 728 are at least 1318 bytes available to split among the key, key_prefix and value. If the total size of the command, including overhead, exceeds 1400 bytes, a <a class="reference internal" href="client_errors/MEMCACHED_WRITE_FAILURE.html#c.MEMCACHED_WRITE_FAILURE" title="MEMCACHED_WRITE_FAILURE"><code class="xref c c-type docutils literal notranslate"><span class="pre">MEMCACHED_WRITE_FAILURE</span></code></a> will be returned.</p>
