Dumping data from a server¶

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)¶

Parameters:	ptr -- pointer to `memcached_st` object key -- key string being dumped key_length -- length of the key without any terminating zero 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.
