New Revision: 32874

URL: http://svn.reactos.org/svn/reactos?rev=32874&view=rev
Log:
BroadcastSystemMessage:
- Implement User half only.
- Introduce example use for NtUserMessageCall.
- IntBroadcastSystemMessage is based on Wine LGPL implementation http://www.winehq.org/pipermail/wine-cvs/2008-April/042051.html .
- Wine testing needed to be change by adding message range parameter check. The range was from 0 to -1 and check for resulting errors that conformed to XP.
- Need to move BROADCASTPARM to include/X/X/ntuser.h or other after Dr. Timo finishes header realignment.
