=head1 DESCRIPTION
memcached(1) servers have the ability to increment and decrement keys
the offset passed to it. The value is then returned via the unsigned int
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 unsigned int
+value pointer you pass to it.
