pathname—a pathname designator.
Either binds *standard-input*
and *standard-output*
or takes other appropriate action,
so as to send a record of the input/output interaction to a file
named by pathname. dribble
is intended to create
a readable record of an interactive session.
If pathname is a logical pathname, it is translated
into a physical pathname as if by calling translate-logical-pathname
.
(dribble)
terminates the recording of input and output
and closes the dribble file.
If dribble
is called while a stream to a “dribble file”
is still open from a previous call to dribble
,
the effect is implementation-defined. For example,
the already-open stream might be closed,
or dribbling might occur both to the old stream and to a new one,
or the old stream might stay open but not receive any further output,
or the new request might be ignored,
or some other action might be taken.
The implementation.
If a failure occurs when performing some operation on the file system
while creating the dribble file,
an error of type file-error
is signaled.
An error of type file-error
might be signaled if pathname
is a designator for a wild pathname.
Section 19.1.2 (Pathnames as Filenames)
dribble
can return before subsequent
forms are executed. It also
can enter a recursive interaction loop,
returning only when (dribble)
is done.
dribble
is intended primarily for interactive debugging;
its effect cannot be relied upon when used in a program.
