// History: 23-Jul-91 KyleP Created.
|
|
// 09-Oct-91 KevinRo Major changes and comments added
|
|
// 18-Oct-91 vich moved debug print routines out
|
|
// 10-Jun-92 BryanT Switched to w4crt.h instead of wchar.h
|
|
// 30-Sep-93 KyleP DEVL obsolete
|
|
// 7-Oct-94 BruceFo Ripped out all kernel, non-FLAT,
|
|
// DLL-specific, non-Win32 functionality.
|
|
// Now it's basically "print to the
|
|
// debugger" code.
|
|
// 20-Oct-95 EricB Set component debug level in the
|
|
// registry.
|
|
// 23-Feb-01 JBenton Added code to clean up crit sections
