.SH NAME
Tk_GetSelection \- retrieve the contents of a selection
.SH SYNOPSIS
.nf
\fB#include <tk.h>\fR
.sp
int
\fBTk_GetSelection\fR(\fIinterp, tkwin, selection, target, proc, clientData\fR)
.SH ARGUMENTS
.AS Tk_GetSelProc clientData
.AP Tcl_Interp *interp in
Interpreter to use for reporting errors.
.AP Tk_Window tkwin in
Window on whose behalf to retrieve the selection (determines
display from which to retrieve).
.AP Atom selection in
The name of the selection to be retrieved.
.AP Atom target in
Form in which to retrieve selection.
.AP Tk_GetSelProc *proc in
Procedure to invoke to process pieces of the selection as they
are retrieved.
.AP ClientData clientData in
Arbitrary one-word value to pass to \fIproc\fR.
.BE

.SH DESCRIPTION
.PP
\fBTk_GetSelection\fR retrieves the selection specified by the atom
\fIselection\fR in the format specified by \fItarget\fR.  The
selection may actually be retrieved in several pieces; as each piece
is retrieved, \fIproc\fR is called to process the piece.  \fIProc\fR
should have arguments and result that match the type
\fBTk_GetSelProc\fR:
.CS
typedef int Tk_GetSelProc(
	ClientData \fIclientData\fR,
	Tcl_Interp *\fIinterp\fR,
	char *\fIportion\fR);
.CE
The \fIclientData\fR and \fIinterp\fR parameters to \fIproc\fR 
will be copies of the corresponding arguments to
\fBTk_GetSelection\fR.  \fIPortion\fR will be a pointer to
a string containing part or all of the selection.  For large
selections, \fIproc\fR will be called several times with successive
portions of the selection.  The X Inter-Client Communication
Conventions Manual allows a selection to be returned in formats
other than strings, e.g. as an array of atoms or integers.  If
this happens, Tk converts the selection back into a string
before calling \fIproc\fR.  If a selection is returned as an
array of atoms, Tk converts it to a string containing the atom names
separated by white space.  For any other format besides string,
Tk converts a selection to a string containing hexadecimal
values separated by white space.
.PP
\fBTk_GetSelection\fR returns to its caller when the selection has
been completely retrieved and processed by \fIproc\fR, or when a
fatal error has occurred (e.g. the selection owner didn't respond
promptly).  \fBTk_GetSelection\fR normally returns TCL_OK;  if
an error occurs, it returns TCL_ERROR and leaves an error message
in \fIinterp->result\fR.  \fIProc\fR should also return either
TCL_OK or TCL_ERROR. If \fIproc\fR encounters an error in dealing with the
selection, it should leave an error message in \fIinterp->result\fR
and return TCL_ERROR;  this will abort the selection retrieval.

276	\fBTk_GetSelection\fR retrieves the selection specified by the atom
277	\fIselection\fR in the format specified by \fItarget\fR. The
278	selection may actually be retrieved in several pieces; as each piece
279	is retrieved, \fIproc\fR is called to process the piece. \fIProc\fR
280	should have arguments and result that match the type

287	.CE
288	The \fIclientData\fR and \fIinterp\fR parameters to \fIproc\fR
289	will be copies of the corresponding arguments to
290	\fBTk_GetSelection\fR. \fIPortion\fR will be a pointer to
291	a string containing part or all of the selection. For large
292	selections, \fIproc\fR will be called several times with successive
293	portions of the selection. The X Inter-Client Communication
294	Conventions Manual allows a selection to be returned in formats
295	other than strings, e.g. as an array of atoms or integers. If
296	this happens, Tk converts the selection back into a string
297	before calling \fIproc\fR. If a selection is returned as an
298	array of atoms, Tk converts it to a string containing the atom names
299	separated by white space. For any other format besides string,
300	Tk converts a selection to a string containing hexadecimal
301	values separated by white space.
302	.PP
303	\fBTk_GetSelection\fR returns to its caller when the selection has
304	been completely retrieved and processed by \fIproc\fR, or when a
305	fatal error has occurred (e.g. the selection owner didn't respond
306	promptly). \fBTk_GetSelection\fR normally returns TCL_OK; if
307	an error occurs, it returns TCL_ERROR and leaves an error message
308	in \fIinterp->result\fR. \fIProc\fR should also return either
309	TCL_OK or TCL_ERROR. If \fIproc\fR encounters an error in dealing with the
310	selection, it should leave an error message in \fIinterp->result\fR
311	and return TCL_ERROR; this will abort the selection retrieval.
