Vector streams are similar to STRING streams but use vectors of
(UNSIGNED-BYTE 8) and allow binary as well as character I/O.

[Type][[BR]]
'''VECTOR-INPUT-STREAM'''

Type of input vector streams.

[Type][[BR]]
'''VECTOR-OUTPUT-STREAM'''

Type of output vector streams.

[Function][[BR]]
'''MAKE-VECTOR-OUTPUT-STREAM''' `&key external-format`

Returns a VECTOR-OUTPUT-STREAM. Character output on that
stream is encoded according to the specified external format
(which is handled as it is by other CCL stream classes.)

[Function][[BR]]
'''GET-OUTPUT-STREAM-VECTOR''' `s`

S should be a VECTOR-OUTPUT-STREAM. Returns a (SIMPLE-ARRAY
(UNSIGNED-BYTE) (*)) of all bytes written to S since it was
created or since the last call GET-OUTPUT-STREAM-VECTOR on S.

[Macro][[BR]]
'''WITH-OUTPUT-TO-VECTOR''' `var &optional vector &key external-format &body body`

Like WITH-OUTPUT-TO-STRING (too much like it, in fact.)
Executes BODY with VAR bound to a VECTOR-OUTPUT-STREAM. If VECTOR is
non-null, it should be a (VECTOR (UNSIGNED-BYTE 8)) with a fill-pointer;
the value(s) returned by BODY are returned and the vector's contents
and fill-pointer are updated at the end of the WITH-OUTPUT-TO-VECTOR form.
If VECTOR is NIL, returns the result of (GET-OUTPUT-STREAM-VECTOR var) after
executing BODY.

[Macro][[BR]]
'''WITH-INPUT-FROM-VECTOR''' `var vector &key (start 0) end external-format &body body`

Like WITH-INPUT-FROM-STRING. VECTOR should be a (VECTOR (UNSIGNED-BYTE 8)).
Executes BODY with VAR bound to a VECTOR-INPUT-STREAM constructed from
VECTOR (bounded by START and END.)

[Function][[BR]]
'''UNSIGNED-INTEGER-TO-BINARY''' `value len s`

Encodes the least significant (* LEN 8) bits of the integer VALUE in LEN big-endian bytes on the VECTOR-OUTPUT-STREAM S. 


[Function][[BR]]
'''SIGNED-INTEGER-TO-BINARY''' `value len s`

Encodes the integer VALUE in LEN big-endian bytes on the VECTOR-OUTPUT-STREAM S. 

[Function][[BR]]
'''PARSE-UNSIGNED-INTEGER''' `vector &optional (start 0) end`

Decodes a big-endian-encoded unsigned integer from the bounded range of VECTOR,
which must be of type (VECTOR (UNSIGNED-BYTE 8)). 

[Function][[BR]]
'''PARSE-SIGNED-INTEGER''' `vector &optional (start 0) end`

As PARSE-UNSIGNED-INTEGER, but interprets the bytes as encoding a signed integer and may return
a negative value.

[Function][[BR]]
'''PUI-STREAM''' `s count`

Decodes an unsigned integer encoded in COUNT bytes of big-endian data from the VECTOR-INPUT-STREAM S and
returns that value.

[Function][[BR]]
'''PSI-STREAM''' `s count`


Decodes a signed integer encoded in COUNT bytes of big-endian data from the VECTOR-INPUT-STREAM S and
returns that value.
