A select set is a wrapper around a select or poll implementation. The advantages are, that the user does not have to care about the final implementation (select or poll) and the set stores the status. If events for buffered handles are received, the implementation processes it silently and notifies the user only if a whole data block has arrived or the connection is writable again. Keepalive as well as control messages, packed in error info blocks, can be processed hidden. Most applications, e.g. dispatcher or SAProuter, use these select sets.
