       memcached_dump - libmemcached Documentation

SYNOPSIS

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

       typedef memcached_return_t (*memcached_dump_fn)(memcached_st *ptr, const char *key, size_t key_length,
       void *context)

              Param ptr
                     pointer to memcached_st object

              Param key
                     key string being dumped

              Param key_length
                     length of the key without any terminating zero

              Param context
                     pointer to the user supplied context

              Returns
                     memcached_return_t indicating success

       memcached_return_t memcached_dump(memcached_st *ptr, memcached_dump_fn *function, void *context, uint32_t
       number_of_callbacks)

              Parameters

                     • ptr -- pointer to initialized memcached_st struct

                     • function -- pointer to number_of_callbacks memcached_dump_fn callbacks

                     • context -- pointer to a user managed context

                     • number_of_callbacks -- number of callbacks in the function array

              Returns
                     memcached_return_t indicating success

DESCRIPTION

       memcached_dump()  is used to get a list of keys found in memcached(1) servers. Because memcached does not
       guarantee to dump all keys you can not assume you have fetched all keys from  the  server.  The  function
       takes an array of callbacks that it will use to execute on keys as they are found.

       Currently the binary protocol is not tested.

RETURN VALUE

       A  value  of  type memcached_return_t is returned.  On success that value will be MEMCACHED_SUCCESS.  Use
       memcached_strerror() to translate this value to a printable string.
