NAME

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

SYNTAX

       #include <X11/Intrinsic.h>

       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.
