+.TH Tk_GetSelection 3 4.0 Tk "Tk Library Procedures"
+.\" The -*- nroff -*- definitions below are for supplemental macros used

+.\"
+.\" .AP type name in/out ?indent?
+.\" Start paragraph describing an argument to a library procedure.
+.\" type is type of argument (int, etc.), in/out is either "in", "out",
+.\" or "in/out" to describe whether procedure reads or modifies arg,
+.\" and indent is equivalent to second arg of .IP (shouldn't ever be
+.\" needed; use .AS below instead)
+.\"
+.\" .AS ?type? ?name?
+.\" Give maximum sizes of arguments for setting tab stops. Type and
+.\" name are examples of largest possible arguments that will be passed
+.\" to .AP later. If args are omitted, default tab stops are used.
+.\"
+.\" .BS
+.\" Start box enclosure. From here until next .BE, everything will be
+.\" enclosed in one large box.

+.\" of man pages. The first argument is ignored and used for recording
+.\" the version when the .VS was added, so that the sidebars can be

+.\"
+.\" .DE
+.\" End of indented unfilled display.

+.\" argument defines where to look up the standard options; if
+.\" omitted, defaults to "options". The options follow on successive
+.\" lines, in three columns separated by tabs.
+.\"
+.\" .SE
+.\" End of list of standard options for a Tk widget.
+.\"
+.\" .OP cmdName dbName dbClass
+.\" Start of description of a specific option. cmdName gives the

+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:
+.PP
+.CS
+typedef int \fBTk_GetSelProc\fR(
+ ClientData \fIclientData\fR,
+ Tcl_Interp *\fIinterp\fR,
+ char *\fIportion\fR);
+.CE
+.PP
+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 did not respond
+promptly). \fBTk_GetSelection\fR normally returns \fBTCL_OK\fR; if
+an error occurs, it returns \fBTCL_ERROR\fR and leaves an error message
+in interpreter \fIinterp\fR's result. \fIProc\fR should also return either
+\fBTCL_OK\fR or \fBTCL_ERROR\fR. If \fIproc\fR encounters an error in
+dealing with the selection, it should leave an error message in the
+interpreter result and return \fBTCL_ERROR\fR; this will abort the
+selection retrieval.
