DESCRIPTION
-***********
+-----------
memcached_set(), memcached_add(), and memcached_replace() are all used to
store information on the server. All methods take a key, and its length to
store the object. Keys are currently limited to 250 characters by the
memcached(1) server. You must also supply a value and a length. Optionally you
-may support an expiration time for the object and a 16 byte value (it is
+may tests an expiration time for the object and a 16 byte value (it is
meant to be used as a bitmap).
memcached_set() will write an object to the server. If an object already
memcached_cas() overwrites data in the server as long as the "cas" value is
still the same in the server. You can get the cas value of a result by
calling memcached_result_cas() on a memcached_result_st(3) structure. At the point
-that this note was written cas is still buggy in memached. Turning on support
+that this note was written cas is still buggy in memached. Turning on tests
for it in libmemcached(3) is optional. Please see memcached_set() for
information on how to do this.
memcached_set_by_key(), memcached_add_by_key(), memcached_replace_by_key(),
memcached_prepend_by_key(), memcached_append_by_key_by_key(),
memcached_cas_by_key() methods all behave in a similar method as the non key
-methods. The difference is that they use their master_key parameter to map
+methods. The difference is that they use their group_key parameter to map
objects to particular servers.
If you are looking for performance, memcached_set() with non-blocking IO is
the fastest way to store data on the server.
-All of the above functions are supported with the \ ``MEMCACHED_BEHAVIOR_USE_UDP``\
+All of the above functions are testsed with the \ ``MEMCACHED_BEHAVIOR_USE_UDP``\
behavior enabled. But when using these operations with this behavior on, there
are limits to the size of the payload being sent to the server. The reason for
these limits is that the Memcahed Server does not allow multi-datagram requests
will be returned.

All methods return a value of type \ ``memcached_return_t``\ .
legitmate error in the case of a collision.
