The generic function stream-write-sequence
is used by write-sequence
to write a subsequence of sequence delimited by start and end to stream.
A default method is provided by fundamental-character-output-stream
that tests each element of sequence in turn, and then uses stream-write-char
or produces an error. A default method is provided by fundamental-binary-output-stream
that tests each element of sequence in turn, and then uses stream-write-byte
or produces an error.
