   7 #include <libmemcached/memcached.h>
   8     Compile and link with -lmemcached
   9
  10 .. type:: memcached_return_t (*memcached_dump_fn)(memcached_st *ptr, const char *key, size_t key_length, void *context)
  11
  12     :param ptr: pointer to `memcached_st` object
  13     :param key: key string being dumped
  14     :param key_length: length of the key without any terminating zero
  15     :param context: pointer to the user supplied context
  16     :returns: `memcached_return_t` indicating success
  17
  18 .. function:: memcached_return_t memcached_dump (memcached_st *ptr, memcached_dump_fn *function, void *context, uint32_t number_of_callbacks)
  19
  20     :param ptr: pointer to initialized `memcached_st` struct
  21     :param function: pointer to `number_of_callbacks` `memcached_dump_fn` callbacks
  22     :param context: pointer to a user managed context
  23     :param number_of_callbacks: number of callbacks in the `function` array
  24     :returns: `memcached_return_t` indicating success

  27 DESCRIPTION
  28 -----------
  29
  30 :func:`memcached_dump` is used to get a list of keys found in :manpage:`memcached(1)`
  31 servers. Because memcached does not guarantee to dump all keys you can not
  32 assume you have fetched all keys from the server. The function takes an array
  33 of callbacks that it will use to execute on keys as they are found.
  34
  35 Currently the binary protocol is not tested.
  36
  37 RETURN VALUE
  38 ------------
  39
  40 A value of type :type:`memcached_return_t` is returned.
  41 On success that value will be `MEMCACHED_SUCCESS`.
  42 Use :func:`memcached_strerror` to translate this value to a printable
  43 string.
