 * resource.c - resource management for xlock, the X Window System lockscreen.
 *
 * Copyright (c) 1991 by Patrick J. Naughton.
 *
 * See xlock.c for copying information.
 *
 * Revision History:
 *
 * Changes maintained by David Bagley <bagleyd AT verizon.net>
 * 02-Dec-03: Jouk Jansen <joukj AT hrem.nano.tudelft.nl>
 *            On OpenVMS when TCPIP is switched off gethostname does not
 *            work, in that case LIB$GETSYI to get the DECNET nodename.
 * 19-Jun-98: batchcount deprecated.  Use count instead.  batchcount still
 *            works for commandline.
 * 01-May-97: Matthew Rench <mdrench@mtu.edu>
 *            Added DPMS options.
 * 01-Apr-97: Tom Schmidt <tschmidt AT micron.com>
 *            Fixed memory leak.  Made -visual option a hacker mode for now.
 * 20-Mar-97: Tom Schmidt <tschmidt AT micron.com>
 *            Added -visual option.
 *  3-Apr-96: Jouk Jansen <joukj AT hrem.nano.tudelft.nl>
 *            Supply for wildcards for filenames for random selection
 * 18-Mar-96: Ron Hitchens <ron AT idiom.com>
 *            Setup chosen mode with set_default_mode() for new hook scheme.
 *  6-Mar-96: Jouk Jansen <joukj AT hrem.nano.tudelft.nl>
 *            Remote node checking for VMS fixed
 * 20-Dec-95: Ron Hitchens <ron AT idiom.com>
 *            Resource parsing fixed for "nolock".
 * 02-Aug-95: Patch to use default delay, etc., from mode.h thanks to
 *            Roland Bock <exp120@physik.uni-kiel.d400.de>
 * 17-Jun-95: Split out mode.h from resource.c .
 * 29-Mar-95: Added -cycles for more control over a lockscreen similar to
 *            -delay, -batchcount, and -saturation.
 * 21-Feb-95: MANY patches from Heath A. Kehoe <hakehoe AT icaen.uiowa.edu>.
 * 21-Dec-94: patch for -delay, -batchcount and -saturation for X11R5+
 *            from Patrick D Sullivan <pds@bss.com>.
 * 18-Dec-94: -inroot option added from Bill Woodward <wpwood@pencom.com>.
 * 20-Sep-94: added bat mode from Lorenzo Patocchi <patol@info.isbiel.ch>.
 * 11-Jul-94: added grav mode, and inwindow option from Greg Bowering
 *            <greg@cs.adelaide.edu.au>
 * 22-Jun-94: Modified for VMS
 *            <Anthony.D.Clarke@Support.Hatfield.Raytheon.bae.eurokom.ie>
 * 17-Jun-94: default changed from life to blank
 * 21-Mar-94: patch fix for AIXV3 from <R.K.Lloyd@csc.liv.ac.uk>
 * 01-Dec-93: added patch for AIXV3 from Tom McConnell
 *            <tmcconne@sedona.intel.com>
 * 29-Jun-93: added spline, maze, sphere, hyper, helix, rock, and blot mode.
 *
 * Changes of Patrick J. Naughton
 * 25-Sep-91: added worm mode.
 * 24-Jun-91: changed name to username.
 * 06-Jun-91: Added flame mode.
 * 24-May-91: Added -name and -usefirst and -resources.
 * 16-May-91: Added random mode and pyro mode.
 * 26-Mar-91: checkResources: delay must be >= 0.
 * 29-Oct-90: Added #include <ctype.h> for missing isupper() on some OS revs.
 *	      moved -mode option, reordered Xrm database evaluation.
 * 28-Oct-90: Added text strings.
 * 26-Oct-90: Fix bug in mode specific options.
 * 31-Jul-90: Fix ':' handling in parsefilepath
