/*
 * KillClick2 - by Daniel Martin
 * December 14th, 1990.
 * USENET: martin@IRO.UMontreal.CA
 *
 * Based on KillClick Written by Brian Gontowski
 *
 * Modifications:
 *		- Now turn off all connected drive units
 *		- "#includes" controlled by a switch for compilation with MANX Aztec
 *		- Use TD_NAME instead of "trackdisk.device" for compatibility
 *		- Added prototyping for AINSI C compliance
 *		- Shortened error messages, users don't know much of this stuff anyway.
 *
 * Bugs: 
 *		None.
 *
 * Remarks: 
 *		I'm not sure if we should put forbid()/permit() when modifying the public 
 *		structure TDU_PublicUnit in NoClick procedure.
