(EXT:MAKE-BUFFERED-OUTPUT-STREAM
. Returns a buffered output function
)STREAM
.
function
is a FUNCTION
expecting one argument, a SIMPLE-STRING
.
WRITE-CHAR
collects the CHARACTER
s in a STRING
, until a
newline character is written or FORCE-OUTPUT
/FINISH-OUTPUT
is called.
Then function
is called with a SIMPLE-STRING
as argument,
that contains the characters collected so far.
CLEAR-OUTPUT
discards the characters collected so far.
(EXT:MAKE-BUFFERED-INPUT-STREAM
. Returns a buffered input function
mode
)STREAM
.
function
is a FUNCTION
of 0 arguments that returns
either NIL
(stands for end-of-stream
) or up to three values
string
, start
, end
.
READ-CHAR
returns the CHARACTER
s of the current string
one
after another, as delimited by start
and end
, which default to
0
and NIL
, respectively.
When the string
is consumed, function
is called again.
The string
returned by function
should not be changed by the user.
function
should copy the string
with COPY-SEQ
or SUBSEQ
before
returning if the original string
is to be modified.
mode
determines the behavior of LISTEN
when the current string
buffer is empty:
NIL
FILE-STREAM
,
i.e. function
is calledT
end-of-stream
, i.e. one can assume that further characters will always
arrive, without calling function
FUNCTION
FUNCTION
tells, upon call, if further
non-empty string
s are to be expected.
CLEAR-INPUT
discards the rest of the current string
,
so function
will be called upon the next READ-CHAR
operation.
