XtCreateSelectionRequest(3)					   XT FUNCTIONS 				       XtCreateSelectionRequest(3)

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 mul-
       tiple 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.
