One of the most important responsibilities of a data transport service provider is providing indications to the client when certain network events have occurred. The following list shows defined network events:
- FD_CONNECT - A connection to a remote host or to a multicast
session has been completed
- FD_ACCEPT - A remote host is making a connection request
- FD_READ - Network data has arrived which is available to be
read
- FD_WRITE - Space has become available in the service provider's
buffers so that additional data may now be sent
- FD_OOB - Out of band data is available to be read
- FD_CLOSE - The remote host has closed down the connection
- FD_ROUTING_INTERFACE_CHANGE – A local interface that should be
used to reach the destination specified in
SIO_ROUTING_INTERFACE_CHANGE IOCTL has changed
- FD_ADDRESS_LIST_CHANGE – The list of local addresses to which
application can bind has changed
The preceding set of network events enumerated is sometimes referred to as the FD_XXX events. Indication of the occurrence of one or more of such network events may be given in a number of ways depending on how the client requests for notification.
