Deprecated since version 0.50: Use memcached_fetch_result() instead.
Compile and link with -lmemcached
memcached_fetch() is used to fetch an individual value from the server. 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 uint32_t pointer to contain whatever flags you stored with the value, a size_t pointer which will be filled with size of of the object, and a memcached_return_t pointer to hold any error. The object will be returned upon success and NULL will be returned on failure. MEMCACHED_END is returned by the *error value when all objects that have been found are returned. The final value upon MEMCACHED_END is null.
Values returned by memcached_fetch() must be freed by the caller.
All of the above functions are not tested when the MEMCACHED_BEHAVIOR_USE_UDP has been set. Executing any of these functions with this behavior on will result in MEMCACHED_NOT_SUPPORTED being returned, or for those functions which do not return a memcached_return_t, the error function parameter will be set to MEMCACHED_NOT_SUPPORTED.
