NAME

       XtCreateSelectionRequest, XtSendSelectionRequest, XtCancelSelectionRequest - bundle multiple selection
       conversion requests into a single request using MULTIPLE target

SYNTAX

       void XtCreateSelectionRequest(Widget requestor, Atom selection):

       void XtSendSelectionRequest(Widget requestor, Atom selection, Time time);

       void XtCancelSelectionRequest(Widget requestor, Atom selection);

ARGUMENTS

       requestor Specifies the widget making the request. Must be of class Core or a subclass thereof.

       selection Specifies the particular selection desired.

       time      Specifies the timestamp to be used in making the request.

DESCRIPTION

       When XtCreateSelectionRequest is called, subsequent calls to XtGetSelectionValue and
       XtGetSelectionValueIncremental with the requestor and selection as specified to XtCreateSelectionRequest
       will be bundled into a single selection conversion request with multiple targets. The request is actually
       initiated by calling XtSendSelectionRequest.

       When XtSendSelectionRequest is called with a value of requestor and selection matching a previous call to
       XtCreateSelectionRequest, a selection conversion request is actually sent to the selection owner.  If a
       single target request is queued, that request is made. If multiple targets are queued they are bundled
       into a single request with the target MULTIPLE using the specified timestamp. As the conversions are
       made, the callbacks associated with each XtGetSelectionValue and XtGetSelectionValueIncremental are
       invoked in turn.

       Multi-threaded applications should lock the application context before calling XtCreateSelectionRequest
       and release the lock after calling XtSendSelectionRequest to ensure that the thread assembling the
       request is safe from interference by another thread assembling a different request naming the same widget
       and selection.

       When XtCancelSelectionRequest is called, any requests queued since the last call to
       XtCreateSelectionRequest are cleaned up. Subsequent calls to XtGetSelectionValue, XtGetSelectionValues,
       XtGetSelectionValueIncremental, and XtGetSelectionValuesIncremental will not be deferred.
