/*
* INTERNAL.C - command.com internal commands.
*
*
* History:
*
* 17/08/94 (Tim Norman)
* started.
*
* 08/08/95 (Matt Rains)
* i have cleaned up the source code. changes now bring this source into
* guidelines for recommended programming practice.
*
* cd()
* started.
*
* dir()
* i have added support for file attributes to the DIR() function. the
* routine adds "d" (directory) and "r" (read only) output. files with the
* system attribute have the filename converted to lowercase. files with
* the hidden attribute are not displayed.
*
* i have added support for directorys. now if the directory attribute is
* detected the file size if replaced with the string "<dir>".
*
* ver()
* started.
*
* md()
* started.
*
* rd()
* started.
*
* del()
* started.
*
* does not support wildcard selection.
*
* todo: add delete directory support.
* add recursive directory delete support.
*
* ren()
* started.
*
* does not support wildcard selection.
*
* todo: add rename directory support.
*
* a general structure has been used for the cd, rd and md commands. this
* will be better in the long run. it is too hard to maintain such diverse
* functions when you are involved in a group project like this.
*
* 12/14/95 (Tim Norman)
* fixed DIR so that it will stick \*.* if a directory is specified and
* that it will stick on .* if a file with no extension is specified or
* *.* if it ends in a \
*
* 1/6/96 (Tim Norman)
* added an isatty call to DIR so it won't prompt for keypresses unless
* stdin and stdout are the console.
*
* changed parameters to be mutually consistent to make calling the
* functions easier
*
* rem()
* started.
*
* doskey()
* started.
*
* 01/22/96 (Oliver Mueller)
* error messages are now handled by perror.
*
* 02/05/96 (Tim Norman)
* converted all functions to accept first/rest parameters
*
* 07/26/96 (Tim Norman)
* changed return values to int instead of void
*
* path() started.
*
* 12/23/96 (Aaron Kaufman)
* rewrote dir() to mimic MS-DOS's dir
*
* 01/28/97 (Tim Norman)
* cleaned up Aaron's DIR code
*
* 06/13/97 (Tim Norman)
* moved DIR code to dir.c
* re-implemented Aaron's DIR code
*
* 06/14/97 (Steffan Kaiser)
* ctrl-break handling
* bug fixes
*
* 27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
* added config.h include
*
* 03-Dec-1998 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Replaced DOS calls by Win32 calls.
*
* 08-Dec-1998 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Added help texts ("/?").
*
* 18-Dec-1998 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Added support for quoted arguments (cd "program files").
*
* 07-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Clean up.
*
* 26-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Replaced remaining CRT io functions by Win32 io functions.
* Unicode safe!
*
* 30-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Added "cd -" feature. Changes to the previous directory.
*
* 15-Mar-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Fixed bug in "cd -" feature. If the previous directory was a root
* directory, it was ignored.
*
* 23-Feb-2001 (Carl Nettelblad <cnettel@hem.passagen.se>)
* Improved chdir/cd command.
*
* 02-Apr-2004 (Magnus Olsen <magnus@greatlord.com>)
* Remove all hard code string so they can be
* translate to other langues.
*
* 19-jul-2005 (Brandon Turner <turnerb7@msu.edu)
* Rewrite the CD, it working as Windows 2000 CMD
*
* 19-jul-2005 (Magnus Olsen <magnus@greatlord.com)
* Add SetRootPath and GetRootPath
