//  History:    23-Jul-91   KyleP       Created.
//              15-Oct-91   KevinRo     Major changes and comments added

//              29-Apr-92   BartoszM    Moved from win4p.h
//              18-Jun-94   AlexT       Make Assert a better statement
//               7-Oct-94   BruceFo     Stole and ripped out everything except
//                                      debug prints and asserts.
//              20-Oct-95   EricB       Set component debug level in the
//                                      registry.
//              26-Feb-96   EricB       Renamed Win4xxx exported fcns to not
//                                      conflict with ole32.lib.
//
//
//  NOTE: you must call the InitializeDebugging() API before calling any other
//  APIs!
//
//  To set a non-default debug info level outside of the debugger, create the
//  below registry key:
//
//   "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AdminDebug"
//
//  and in it create a value whose name is the component's debugging tag name
//  (the "comp" parameter to the DECLARE_INFOLEVEL macro) and whose data is
//  the desired infolevel in REG_DWORD format.
//  e.g. Sched = REG_DWORD 0x707

//
// This macro defines xxDebugOut where xx is the component prefix
// to be defined. This declares a static variable 'xxInfoLevel', which
// can be used to control the type of xxDebugOut messages printed to
// the terminal. For example, xxInfoLevel may be set at the debug terminal.
// This will enable the user to turn debugging messages on or off, based
// on the type desired. The predefined types are defined below. Component
// specific values should use the upper 24 bits
//
// To Use:
//
// 1)   In your components main include file, include the line
//              DECLARE_DEBUG(comp)
//      where comp is your component prefix
//
// 2)   In one of your components source files, include the line
//              DECLARE_INFOLEVEL(comp)
//      where comp is your component prefix. This will define the
//      global variable that will control output.
//
// It is suggested that any component define bits be combined with
// existing bits. For example, if you had a specific error path that you
// wanted, you might define DEB_<comp>_ERRORxxx as being
//
// (0x100 | DEB_ERROR)
//
// This way, we can turn on DEB_ERROR and get the error, or just 0x100
// and get only your error.
