Maybe I’m doing something silly, but this looks like the ?? C++
Evaluation operator isn’t getting along with the range syntax? (I’m
using 6.7.5.1.) Please point out the error of my ways, or maybe this is
a bug or just something that isn’t supported. Thanks!
i dont think you can use double question marks on L like L??
i mean i havent done it that way and according to the help file i
think its just a single ?
like L?0x99c60
may be you could try r $t0 = trace####->tracehead
L?$t0
hope that helps

yes you have to assign the evaluated expression or yo can probably try
bracketing it like L? (?? Trace####->Tracehaead)

r $t0 = windbg

It’s not just the “L” portion; this also gives the same syntax error: kd> .writemem trace.2.log ??((void *)Trace!traceDeviceExtension->pTraceBuffer) L8 Syntax error at '??((void *)Trace!traceDeviceExtension->pTraceBuffer) '

Actually, I ended up just changing the cases of ?? in my original commands into @@ and it worked fine. I don’t understand why or what the difference between the two is, but it worked.
