 .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.
