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.
