Would you believe:
KdPrint((“My value is %d\n”, nMyValue));

Subject: [ntdev] A quick one: sprintf in KM?
Hi guys,
Sorry to bother you with such a silly question 
but here goes:
What’s the quickest way of sending a formatted output from a km driver
to WinDbg?
Something along these lines:
:
char szBuffer[64];
short nMyValue;
:
sprintf (szBuffer, “My value is %d”, nMyValue);
DbgPrint (szBuffer);
:
I would ‘#include <stdio.h>’ (DDK won’t complain) but I’m not sure if
it’s
advisable… Of course, I could use ‘RtlIntegerToUnicodeString’
followed by a
couple of DbgPrint calls… but isn’t there an easy way (or does
#include <stdio.h>
work just fine)?
(P.S. - Of course I have access to ‘nMyValue’ on WinDbg; it’s just that
I would
like to quickly check some changing values inside a short loop, without
having
to break in all the time…)
Thanx,
Miguel Monteiro

OK, I was happy to help, but your response leads to an obvious question.
Did you not read the docs on DbgPrint, which explicitly state that DbgPrint
supports the same formatting specs as printf, before asking your question?

Anyway, Phil Barila and Max gave a good tip (I wasn’t sure
DbgPrint/KdPrint supported the same syntax).

Just a note on DbgPrint:
Better do not use something like ‘DbgPrint(lpSomeString)’. If
lpSomeString is Data that you do not directly control(e.g. contents of
packet). It may happen that the string has format identifiers in it.
This leads to unpredictable results.
To circumvent that use ‘DbgPrint(“%s”,lpSomeString)’.
Sorry, if this was to obvious and trivial ?
By the way: Does a not interpreting output function exist ?
