Support for Scatter/Gather I/O
, and WSARecvFrom
functions all take an array of application buffers as input parameters and
can be used for scatter/gather (or vectored) I/O. This can be very useful in
instances where portions of each message being transmitted consist of one or more
fixed-length "header" components in addition to message body. Such header
components need not be concatenated by the application into a single contiguous
buffer prior to sending. Likewise on receiving, the header components can be
automatically split off into separate buffers, leaving the message body "pure."
When receiving into multiple buffers, completion occurs as data arrives from
the network, regardless of whether all the supplied buffers are utilized.
