From: Essie on 13 Oct 2005 20:09 Can someone help to print a UNICODE_STRING to the debig window? The string is in POBJECT_ATTRIBUTES ObjectAttributes ObjectAttributes->ObjectName I believe this is correct so far? But how can I print it, can I use DbgPrint ? DbgPrint(("message %s \n", buffer )); but buffer is normally ansi Thanks

From: Bill McKenzie on 13 Oct 2005 21:12 He meant %wZ and it isn't new, but it didn't used to be documented. Several of the DDK samples use it. Now it is documented with KdPrint(Ex) and DbgPrint(Ex) and the following quote is interesting: "The Format string supports all the printf-style formatting codes. However, the Unicode format codes (%C, %S, %lc, %ls, %wc, %ws, and %wZ) can only be used with IRQL = PASSIVE_LEVEL." Bill M. "Thomas F.

They say we are allowed to use %wZ but they don't say what it does. |
