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)
- Param ptr:
- pointer to - memcached_stobject
- 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_tindicating 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_ststruct
- function -- pointer to - number_of_callbacks- memcached_dump_fncallbacks
- context -- pointer to a user managed context 
- number_of_callbacks -- number of callbacks in the - functionarray
 
- Returns:
- memcached_return_tindicating 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.
