DebugMon question

NTDEV

I was wondering if DebugMon utility displays the DebugPrints/Trace output only with the debug version of the driver or with the release version too?

I would assume only debug version, but just wanted to double-check.

Thanks,

It displays any DebugPrint output, so the answer depends on how the driver
is written. The macros that wrap debugprint are conditionalized by DBG, but
the function can be called from any build type.

I frequently use debug prints in released drivers to note really bad errors
or other unusual conditions.

It will do it for both the debug and the release version for DbgPrint,
of course KdPrint is a macro that expands to nothing for the release
version so you get no output with those.

That depends on your driver. If you use KdPrint, that’s a macro that
disappears in a free build. If you call DbgPrint directly, that always
prints, no matter what build.
