 718 <p><a class="reference internal" href="#c.memcached_prepend" title="memcached_prepend"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_prepend()</span></code></a> and memcached_append are used to
 719 modify information on a server. All methods take a key, and its length to
 720 store the object. Keys are currently limited to 250 characters when using
 721 either a version of memcached which is 1.4 or below, or when using the text
 722 protocol. You must supply both a value and a length. Optionally you
 723 may test an expiration time for the object and a 16 byte value (it is
 724 meant to be used as a bitmap). “flags” is a 4byte space that is stored
 725 alongside of the main value. Many sub libraries make use of this field,
 726 so in most cases users should avoid making use of it.</p>
 727 <p><a class="reference internal" href="#c.memcached_prepend" title="memcached_prepend"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_prepend()</span></code></a> places a segment of data before the last piece
 728 of data stored. Currently expiration and key are not used in the server.</p>
 729 <p><a class="reference internal" href="#c.memcached_append" title="memcached_append"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_append()</span></code></a> places a segment of data at the end of the last
 730 piece of data stored. Currently expiration and key are not used in the server.</p>
 731 <p><a class="reference internal" href="#c.memcached_prepend_by_key" title="memcached_prepend_by_key"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_prepend_by_key()</span></code></a> and
 732 <a class="reference internal" href="#c.memcached_append_by_key" title="memcached_append_by_key"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_append_by_key()</span></code></a> methods both behave in a similar
 733 method as the non key methods. The difference is that they use their
 734 group_key parameter to map objects to particular servers.</p>
 735 <p>If you are looking for performance, <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> with non-blocking
 736 IO is the fastest way to store data on the server.</p>
 737 <p>All of the above functions are testsed with the
 738 <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
 739 these operations with this behavior on, there are limits to the size of the
 740 payload being sent to the server.  The reason for these limits is that the
 741 Memcached Server does not allow multi-datagram requests
 742 and the current server implementation sets a datagram size to 1400 bytes. Due
 743 to protocol overhead, the actual limit of the user supplied data is less than
 744 1400 bytes and depends on the protocol in use as, well as the operation being
 745 executed. When running with the binary protocol,
 746 <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,
 747 flags and expiry combined may not exceed 1368 bytes. When running with the
 748 ASCII protocol, the exact limit fluctuates depending on which function is
 749 being executed and whether the function is a cas operation or not. For
 750 non-cas ASCII set operations, there are at least 1335 bytes available
 751 to split among the key, key_prefix, and value; for cas ASCII operations
 752 there are at least 1318 bytes available to split among the key, key_prefix
 753 and value. If the total size of the command, including overhead, exceeds
 754 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>
