// confdbg.h -  Conferencing Debug Functions and Macros

/*
	The main macros are:

	ASSERT - display error if parameter evalulates to FALSE.
		e.g. ASSERT(x == y);

	ERROR_OUT - always print this error.  Messagebox is optional.
		e.g. ERROR_OUT(("Unable to FooBar!  Err=%d", dwErr));

	WARNING_OUT - warning message, not an error (App must call InitDebugModule)
		e.g. WARNING_OUT(("FooBar is not available. Using %s", szAlt));

	TRACE_OUT - debug message (App must call InitDebugModule)
		e.g. TRACE_OUT(("dwFoo=%d, dwBar=%d", dwFoo, dwBar));

	DBGMSG - debug message for a specific zone
		e.g. DBGMSG(ghZoneFoo, ZONE_BAR, ("Setting dwFoo=%d", dwFoo));


Important Functions:
	VOID DbgInit(HDBGZONE * phDbgZone, PTCHAR * psz, UINT cZone);
	VOID DbgDeInit(HDBGZONE * phDbgZone);
	VOID WINAPI DbgPrintf(PCSTR pszPrefix, PCSTR pszFormat, va_list ap);
	PSTR WINAPI DbgZPrintf(HDBGZONE hZone, UINT iZone, PSTR pszFormat,...);

	Note: The strings in these functions, in particular the module and
	zone names, are always ANSI strings, even in Unicode components.  The
	input strings to DBGINIT should not be wrapped in TEXT macros.
