/* $Id: dir.c,v 1.10 2001/02/28 22:33:23 ekohl Exp $
*
* DIR.C - dir internal command.
*
*
* History:
*
* 01/29/97 (Tim Norman)
* started.
*
* 06/13/97 (Tim Norman)
* Fixed code.
*
* 07/12/97 (Tim Norman)
* Fixed bug that caused the root directory to be unlistable
*
* 07/12/97 (Marc Desrochers)
* Changed to use maxx, maxy instead of findxy()
*
* 06/08/98 (Rob Lake)
* Added compatibility for /w in dir
*
* 06/09/98 (Rob Lake)
* Compatibility for dir/s started
* Tested that program finds directories off root fine
*
* 06/10/98 (Rob Lake)
* do_recurse saves the cwd and also stores it in Root
* build_tree adds the cwd to the beginning of its' entries
* Program runs fine, added print_tree -- works fine.. as EXE,
* program won't work properly as COM.
*
* 06/11/98 (Rob Lake)
* Found problem that caused COM not to work
*
* 06/12/98 (Rob Lake)
* debugged...
* added free mem routine
*
* 06/13/98 (Rob Lake)
* debugged the free mem routine
* debugged whole thing some more
* Notes:
* ReadDir stores Root name and _Read_Dir does the hard work
* PrintDir prints Root and _Print_Dir does the hard work
* KillDir kills Root _after_ _Kill_Dir does the hard work
* Integrated program into DIR.C(this file) and made some same
* changes throughout
*
* 06/14/98 (Rob Lake)
* Cleaned up code a bit, added comments
*
* 06/16/98 (Rob Lake)
* Added error checking to my previously added routines
*
* 06/17/98 (Rob Lake)
* Rewrote recursive functions, again! Most other recursive
* functions are now obsolete -- ReadDir, PrintDir, _Print_Dir,
* KillDir and _Kill_Dir. do_recurse does what PrintDir did
* and _Read_Dir did what it did before along with what _Print_Dir
* did. Makes /s a lot faster!
* Reports 2 more files/dirs that MS-DOS actually reports
* when used in root directory(is this because dir defaults
* to look for read only files?)
* Added support for /b, /a and /l
* Made error message similar to DOS error messages
* Added help screen
*
* 06/20/98 (Rob Lake)
* Added check for /-(switch) to turn off previously defined
* switches.
* Added ability to check for DIRCMD in environment and
* process it
*
* 06/21/98 (Rob Lake)
* Fixed up /B
* Now can dir *.ext/X, no spaces!
*
* 06/29/98 (Rob Lake)
* error message now found in command.h
*
* 07/08/1998 (John P. Price)
* removed extra returns; closer to MSDOS
* fixed wide display so that an extra return is not displayed
* when there is five filenames in the last line.
*
* 07/12/98 (Rob Lake)
* Changed error messages
*
* 27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
* added config.h include
*
*
* 04-Dec-1998 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Converted source code to Win32, except recursive dir ("dir /s").
*
* 10-Dec-1998 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Fixed recursive dir ("dir /s").
*
* 14-Dec-1998 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Converted to Win32 directory functions and
* fixed some output bugs. There are still some more ;)
*
* 10-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Added "/N" and "/4" options, "/O" is a dummy.
* Added locale support.
*
* 20-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Redirection safe!
*
* 01-Mar-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Replaced all runtime io functions by their Win32 counterparts.
*
* 23-Feb-2001 (Carl Nettelblad <cnettel@hem.passagen.se>)
* dir /s now works in deeper trees
