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

DbgPrint(“My value is %d”, nMyValue);
Use KdPrint if you want it to disappear in Free builds.

Any such string must end with \r\n or SoftIce will display them incorrectly.

Just “\n”, but you are absolutely right. I copied it straight from the OP’s
example code, without noticing the obvious. It will eventually show up,
when a newline char finally flushes the buffer, but that’s probably not the
intended behavior, based on the context of the OP’s code.

Thanx Phil, Max.
I wasn’t sure if DbgPrint/KdPrint supported that…

DbgPrint is the right solution for your problem but it could be from
interest for you that sprintf as well as wsprintf and vsprintf are available
in KM (a version of stdio.h is provided with the DDK).

As I said, DDK won’t complain if I simply declare the sprintf function:
int __cdecl sprintf(char *, const char *, …);
he will happily compile the driver and use sprintf… But I wasn’t sure
it was a DDK specific version of stdio.h - that’s why I asked if an
#include <stdio.h> statement would be correct.
Anyway, Phil Barila and Max gave a good tip (I wasn’t sure
DbgPrint/KdPrint supported the same syntax).
Thank you guys,
