 .SH ARGUMENTS
 .AS Tk_ClipboardClear tkwin
 .AP Tcl_Interp *interp in
 Interpreter to use for reporting errors.
 .AP Tk_Window tkwin in
 Window that determines which display's clipboard to manipulate.
 .AP Atom target in
 Conversion type for this clipboard item;  has same meaning as
 \fItarget\fR argument to \fBTk_CreateSelHandler\fR.
 .AP Atom format in
 Representation to use when data is retrieved;  has same meaning as
 \fIformat\fR argument to \fBTk_CreateSelHandler\fR.
 .AP char *buffer in
 Null terminated string containing the data to be appended to the clipboard.
 .BE

 .SH DESCRIPTION
 .PP
 These two procedures manage the clipboard for Tk.
 The clipboard is typically managed by calling \fBTk_ClipboardClear\fR
 once, then calling \fBTk_ClipboardAppend\fR to add data for any
 number of targets.
 .PP
 \fBTk_ClipboardClear\fR claims the CLIPBOARD selection and frees any
 data items previously stored on the clipboard in this application.
 It normally returns TCL_OK, but if an error occurs it returns
 TCL_ERROR and leaves an error message in \fIinterp->result\fR.
 \fBTk_ClipboardClear\fR must be called before a sequence of
 \fBTk_ClipboardAppend\fR calls can be issued.
 .PP
 \fBTk_ClipboardAppend\fR appends a buffer of data to the clipboard.
 The first buffer for a given \fItarget\fR determines the \fIformat\fR
 for that \fItarget\fR.
 Any successive appends for that \fItarget\fR must have
 the same format or an error will be returned.
 \fBTk_ClipboardAppend\fR returns TCL_OK if the buffer is
 successfully copied onto the clipboard.  If the clipboard is not
 currently owned by the application, either
 because \fBTk_ClipboardClear\fR has not been called or because
 ownership of the clipboard has changed since the last call to
 \fBTk_ClipboardClear\fR,
 \fBTk_ClipboardAppend\fR returns TCL_ERROR and leaves an error message in
 \fIinterp->result\fR.
 .PP
 In order to guarantee atomicity, no event handling should occur
 between \fBTk_ClipboardClear\fR and the following
 \fBTk_ClipboardAppend\fR calls (otherwise someone could retrieve
 a partially completed clipboard or claim ownership away from
 this application).
 .PP
 \fBTk_ClipboardClear\fR may invoke callbacks, including arbitrary
 Tcl scripts, as a result of losing the CLIPBOARD selection, so
 any calling function should take care to be reentrant at the point
 \fBTk_ClipboardClear\fR is invoked.
