// History: 23-Jul-91 KyleP Created.

// 15-Oct-91 KevinRo Major changes and comments added
|

|
|
// 18-Oct-91 vich Consolidated win4p.hxx

// 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.
