[xemacs-hg @ 2002-02-22 17:12:26 by michaels] 2002-02-11 Mike Sperber <mike@xemacs.org> * device-x.c: (x_IO_error_handler): (x_init_device): Temporarily keep device in static variable `device_being_initialized' so we can recover gracefully from internal XOpenDevice failure. (XOpenDevice is documented to return NULL on failure, but sometimes calls the IO error handler instead.)
