MEMCACHED_DUMP(3)

NAME
memcached_dump - libmemcached Documentation

SYNOPSIS

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

typedef memcached_return_t <#_CPPv418memcached_return_t> (*memcached_dump_fn)(memcached_st <#_CPPv412memcached_st> *ptr, const char *key, size_t key_length, void *context)

Param ptr
    pointer to memcached_st <#_CPPv412memcached_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 <#_CPPv418memcached_return_t> indicating success

memcached_return_t <#_CPPv418memcached_return_t> memcached_dump(memcached_st <#_CPPv412memcached_st> *ptr, memcached_dump_fn *function, void *context, uint32_t number_of_callbacks)

Parameters

•   ptr -- pointer to initialized memcached_st <#_CPPv412memcached_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 <#_CPPv418memcached_return_t> indicating success

DESCRIPTION

memcached_dump() is used to get a list of keys found in memcached(1) <https://linux.die.net/man/1/memcached> 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 <#_CPPv418memcached_return_t> is returned. On success that value will be MEMCACHED_SUCCESS <#_CPPv4N18memcached_return_t17MEMCACHED_SUCCESSE>. Use memcached_strerror() <#_CPPv418memcached_strerrorP12memcached_st18memcached_return_t> to translate this value to a printable string.
