NAME
       memcached_fetch - Retrieving data from the server

SYNOPSIS
       #include <libmemcached/memcached.h>

       char *memcached_fetch(memcached_st *ptr, char *key, size_t *key_length,
       size_t *value_length, uint32_t *flags, memcached_return_t *error)
              Deprecated since version 0.50: Use memcached_fetch_result()  in-
              stead.

       Compile and link with -lmemcached

DESCRIPTION
       memcached_fetch() is used to fetch an individual value from the server.
       memcached_mget() must always be called before using this  method.   You
       must  pass in a key and its length to fetch the object. You must supply
       three pointer variables which will give you the state of  the  returned
       object.   A  uint32_t pointer to contain whatever flags you stored with
       the value, a size_t pointer which will be filled with size  of  of  the
       object,  and a memcached_return_t pointer to hold any error. The object
       will be returned upon success and NULL will  be  returned  on  failure.
       MEMCACHED_END  is  returned  by  the *error value when all objects that
       have been found are returned. The final  value  upon  MEMCACHED_END  is
       null.

       Values returned by memcached_fetch() must be freed by the caller.

       All  of  the  above  functions are not tested when the MEMCACHED_BEHAV-
       IOR_USE_UDP has been set. Executing any of these  functions  with  this
       behavior  on  will result in MEMCACHED_NOT_SUPPORTED being returned, or
       for those functions which do not return a memcached_return_t, the error
       function parameter will be set to MEMCACHED_NOT_SUPPORTED.

RETURN
       memcached_fetch()  sets  error to to MEMCACHED_END upon successful con-
       clusion.  MEMCACHED_NOTFOUND will be return if  no  keys  at  all  were
       found.

       MEMCACHED_KEY_TOO_BIG  is  set  to error whenever memcached_fetch() was
       used and the key was set larger then MEMCACHED_MAX_KEY, which  was  the
       largest key allowed for the original memcached ascii server.
