read-sequence

write-sequence Functions

Summary

Reads or writes a sequence from or to a stream.

Package

common-lisp

Signatures

read-sequence sequence input-stream &key start end => position

write-sequence sequence output-stream &key start end => sequence

Arguments

`sequence`⇩	A sequence.
`input-stream`⇩	An input stream.
`start`⇩, `end`⇩	Bounding index designators of `sequence`.
`output-stream`⇩	An input stream.

Values

`position`	An index into `sequence`.
`sequence`	A sequence.

Description

The functions read-sequence and write-sequence read and write sequence, bounded by start and end from input-stream or to output-stream, as specified in the ANSI Common Lisp standard.

In LispWorks, read-sequence and write-sequence simply call stream:stream-read-sequence or stream:stream-write-sequence respectively, passing them all the arguments. This allows you to customize the implementation of read-sequence and write-sequence for your own stream classes by defining specialized methods.
