Either <A REL=DEFINITION HREF="26_glo_b.htm#bind"><I>binds</I></A> <A REL=DEFINITION HREF="v_debug_.htm#STstandard-inputST"><B>*standard-input*</B></A> and <A REL=DEFINITION HREF="v_debug_.htm#STstandard-outputST"><B>*standard-output*</B></A> or takes other appropriate action, so as to send a record of the input/output interaction to a file named by <I>pathname</I>. <A REL=DEFINITION HREF="#dribble"><B>dribble</B></A> is intended to create a readable record of an interactive session. <P>
|
||
|
|
If <I>pathname</I> is a <A REL=DEFINITION HREF="26_glo_l.htm#logical_pathname"><I>logical pathname</I></A>, it is translated into a physical pathname as if by calling <A REL=DEFINITION HREF="f_tr_log.htm#translate-logical-pathname"><B>translate-logical-pathname</B></A>. <P>

<TT>(dribble)</TT> terminates the recording of input and output and closes the dribble file. <P>
|

|

If <A REL=DEFINITION HREF="#dribble"><B>dribble</B></A> is <I>called</I> while a <A REL=DEFINITION HREF="26_glo_s.htm#stream"><I>stream</I></A> to a ``dribble file'' is still open from a previous <A REL=DEFINITION HREF="26_glo_c.htm#call"><I>call</I></A> to <A REL=DEFINITION HREF="#dribble"><B>dribble</B></A>, the effect is <A REL=DEFINITION HREF="26_glo_i.htm#implementation-defined"><I>implementation-defined</I></A>. For example, the already-<A REL=DEFINITION HREF="26_glo_o.htm#open"><I>open</I></A> <A REL=DEFINITION HREF="26_glo_s.htm#stream"><I>stream</I></A> might be <A REL=DEFINITION HREF="26_glo_c.htm#closed"><I>closed</I></A>, or dribbling might occur both to the old <A REL=DEFINITION HREF="26_glo_s.htm#stream"><I>stream</I></A> and to a new one, or the old <A REL=DEFINITION HREF="26_glo_s.htm#stream"><I>stream</I></A> might stay open but not receive any further output, or the new request might be ignored, or some other action might be taken. <P>

If a failure occurs when performing some operation on the <A REL=DEFINITION HREF="26_glo_f.htm#file_system"><I>file system</I></A> while creating the dribble file, an error of <A REL=DEFINITION HREF="26_glo_t.htm#type"><I>type</I></A> <A REL=DEFINITION HREF="e_file_e.htm#file-error"><B>file-error</B></A> is signaled. <P>

An error of <A REL=DEFINITION HREF="26_glo_t.htm#type"><I>type</I></A> <A REL=DEFINITION HREF="e_file_e.htm#file-error"><B>file-error</B></A> might be signaled if <I>pathname</I> is a <A REL=DEFINITION HREF="26_glo_d.htm#designator"><I>designator</I></A> for a <A REL=DEFINITION HREF="26_glo_w.htm#wild"><I>wild</I></A> <A REL=DEFINITION HREF="26_glo_p.htm#pathname"><I>pathname</I></A>. <P>
