:action-on-failure-to-open-display

Keyword

Default value: nil

GTK and Motif applications only: if the application uses the X11 code or CAPI, it may fail to run if it cannot open the X display.

In this case, if the value is a function it calls this function with one argument, the display name. The default value of nil means that a message is printed and Lisp quits.
