Debug Messages in Free build

tamarlev

Hello!

I am writing a KMDF driver. I am almost done but...
I want to have the ability to enable\disable debug messages in free version of the driver.

I tried KdPrintEx and DbgPrintEx


DbgPrintEx(DPFLTR_IHVDRIVER_ID, 0, "1 TESTINT DbgPrintEx!@\n");
DbgPrintEx(DPFLTR_IHVDRIVER_ID, 0x33, "2 TESTINT DbgPrintEx!@\n");
DbgPrintEx(DPFLTR_IHVDRIVER_ID, 0x3, "3 TESTINT DbgPrintEx!@\n");

under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Debug Print Filter
i created a DWORD value IHVDRIVER which is set to 0x3.
(tested with 0 and 0x8, etc. etc.)

So what is the right way to do so ? and what i did wrong?

Thanks in advance
Tamar
