upon success and NULL will be returned on failure. MEMCACHD_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() musted be free'ed by the caller.
+memcached_fetch() musted be free'ed by the caller. memcached_fetch() will
+be DEPRECATED in the near future, memcached_fetch_result() should be used
+instead.
memcached_fetch_result() is used to return a memcached_result_st(3) structure
from a memcached server. The result object is forward compatible with changes
memcached_get() and memcached_fetch() will return NULL on error. You must
look at the value of error to determine what the actual error was.
+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.
