Record Streams

Record streams are XDR streams built on top of record fragments, which are built on TCP/IP streams. TCP/IP is a connection protocol for transporting large streams of data at one time rather than transporting a single data packet at a time.

The primary use of a record stream is to interface remote procedure calls to TCP connections. It can also be used to stream data into or out of normal files.

XDR provides the following routines for use with record streams:
