NAME
       memcached_fetch - Retrieving data from the server

SYNOPSIS

       #include <libmemcached/memcached.h>
              Compile and link with -lmemcached

       char *memcached_fetch(memcached_st *ptr, char *key, size_t *key_length,
       size_t *value_length, uint32_t *flags, memcached_return_t *error)
              Deprecated since version 0.50: Use memcached_fetch_result()
              instead.


DESCRIPTION
       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:

          o A uint32_t pointer to contain whatever flags you stored with the
            value,

          o a size_t pointer which will be filled with size of of the object,
            and

          o 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 a NULL
       pointer.

       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.

RETURN VALUE
       memcached_fetch() sets error to to MEMCACHED_END upon successful
       conclusion.

       MEMCACHED_NOTFOUND will be return if no keys at all were found.

       MEMCACHED_KEY_TOO_BIG is set to error whenever memcached_fetch() was
       used and the key was set larger then MEMCACHED_MAX_KEY, which was the
       largest key allowed for the original memcached ascii server.
