.TH XtGetSelectionParameters 3Xt __xorgversion__ "XT FUNCTIONS"
.SH NAME
XtGetSelectionParameters \- retrieve target parameters for a selection request with a single target
.SH SYNTAX
.HP
void XtGetSelectionParameters(Widget \fIowner\fP, Atom \fIselection\fP,
XtRequestId \fIrequest_id\fP, Atom *\fItype_return\fP, XtPointer
*\fIvalue_return\fP, unsigned long *\fIlength_return\fP, int
*\fIformat_return\fP); 
.SH ARGUMENTS
.IP \fIowner\fP 1i
Specifies the widget that owns the specified selection.
.IP \fIselection\fP 1i
Specifies the selection being processed.
.IP \fIrequest_id\fP 1i
Specifies the requestor id in the case of incremental selections, or NULL
in the case of atomic transfers.
.IP \fItype_return\fP 1i
Specifies a pointer to an atom in which the property type of the
parameters will be stored.
.IP \fIvalue_return\fP 1i
Specifies a pointer into which a pointer to the parameters are to be
stored. A NULL will be stored if no parameters accompany the request.
.IP \fIlength_return\fP 1i
Specifies a pointer into which the number of data elements in 
\fIvalue_return\fP of size indicated by \fIformat_return\fP will be
stored.
.IP \fIformat_return\fP 1i
Specifies a pointer into which the size in bits of the parameter data
in the elements of \fIvalue_return\fP will be stored.
.SH DESCRIPTION
.ZN XtGetSelectionParameters
may only be called from within an
.ZN XtConvertSelectionProc
or from within the last call to an
.ZN XtConvertSelectionIncrProc
with a new request_id.
