DESCRIPTION
-----------
(overflow and underflow are not detected). This gives you the ability to use
memcached to generate shared sequences of values.
-memcached_increment takes a key and key length and increments the value by
-the offset passed to it. The value is then returned via the uint32_t
-value pointer you pass to it.
-
-memcached_decrement takes a key and keylength and decrements the value by
-the offset passed to it. The value is then returned via the uint32_t
-value pointer you pass to it.
-
-memcached_increment_with_initial takes a key and keylength and increments
-the value by the offset passed to it. If the object specified by key does
-not exist, one of two things may happen: If the expiration value is
-MEMCACHED_EXPIRATION_NOT_ADD, the operation will fail. For all other
-expiration values, the operation will succeed by seeding the value for that
-key with a initial value to expire with the provided expiration time. The
-flags will be set to zero.The value is then returned via the uint32_t
-value pointer you pass to it. memcached_increment_with_initial is only available
-when using the binary protocol.
-
-memcached_decrement_with_initial takes a key and keylength and decrements
-the value by the offset passed to it. If the object specified by key does
-not exist, one of two things may happen: If the expiration value is
-MEMCACHED_EXPIRATION_NOT_ADD, the operation will fail. For all other
-expiration values, the operation will succeed by seeding the value for that
-key with a initial value to expire with the provided expiration time. The
-flags will be set to zero.The value is then returned via the uint32_t
-value pointer you pass to it. memcached_decrement_with_initial is only available
-when using the binary protocol.

-RETURN
-------
-
-A value of type :type:`memcached_return_t` is returned.
+`memcached_increment` takes a ``key`` and ``key_length`` and increments the
+value by the ``offset`` passed to it. The value is then returned via the
+uint32_t ``value`` pointer you pass to it.
+
+`memcached_decrement` takes a ``key`` and ``key_length`` and decrements the
+value by the ``offset`` passed to it. The value is then returned via the
+uint32_t ``value`` pointer you pass to it.

+``key`` does not exist, one of two things may happen: If the ``expiration``
+value is :c:macro:`MEMCACHED_EXPIRATION_NOT_ADD`, the operation will fail. For
+all other ``expiration`` values, the operation will succeed by seeding the value
+for that key with a initial value to expire with the provided expiration time.
+The ``flags`` will be set to zero. The value is then returned via the uint32_t

+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.
