================= memcached_fetch ================= .. index:: object: memcached_st -------- SYNOPSIS -------- #include .. c:function:: char *memcached_fetch(memcached_st *ptr, char *key, size_t *key_length, size_t *value_length, uint32_t *flags, memcached_return_t *error) .. deprecated:: 0.50 Use :c:func:`memcached_fetch_result` instead. Compile and link with -lmemcached ----------- DESCRIPTION ----------- :c:func:`memcached_fetch` is used to fetch an individual value from the server. :c:func:`memcached_mget` must always be called before using this method. You must pass in a key and its length to fetch the object. You must supply three pointer variables which will give you the state of the returned object. A :c:type:`uint32_t` pointer to contain whatever flags you stored with the value, a :c:type:`size_t` pointer which will be filled with size of of the object, and a :c:type:`memcached_return_t` pointer to hold any error. The object will be returned upon success and NULL will be returned on failure. :c:type:`MEMCACHED_END` is returned by the \*error value when all objects that have been found are returned. The final value upon :c:type:`MEMCACHED_END` is null. Values returned by :c:func:`memcached_fetch` must be freed by the caller. All of the above functions are not tested when the :c:type:`MEMCACHED_BEHAVIOR_USE_UDP` has been set. Executing any of these functions with this behavior on will result in :c:type:`MEMCACHED_NOT_SUPPORTED` being returned, or for those functions which do not return a :c:type:`memcached_return_t`, the error function parameter will be set to :c:type:`MEMCACHED_NOT_SUPPORTED`. ------ RETURN ------ :c:func:`memcached_fetch` sets error to to :c:type:`MEMCACHED_END` upon successful conclusion. :c:type:`MEMCACHED_NOTFOUND` will be return if no keys at all were found. :c:type:`MEMCACHED_KEY_TOO_BIG` is set to error whenever :c:func:`memcached_fetch` was used and the key was set larger then :c:type:`MEMCACHED_MAX_KEY`, which was the largest key allowed for the original memcached ascii server. ---- HOME ---- To find out more information please check: `http://libmemcached.org/ `_ -------- SEE ALSO -------- :manpage:`memcached(1)` :manpage:`libmemcached(3)` :manpage:`memcached_strerror(3)` :manpage:`memcached_fetch_result(3)`
