Changing Irp->IoStatus.Status in a completion routine

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Hi again,

I have one more question. Is it ok to change Irp->IoStatus.Status from STATUS_SUCCESS to an error code in a completion routine? I've found lots of information about completion routines, marking Irps pending and returning STATUS_CONTINUE_COMPLETION or STATUS_MORE_PROCESSING_REQUIRED but so far nothing that tells me if I can legally change the Irp->IoStatus.Status value.

If we can do this, do we need to do anything else like complete the request again, or changing the status value ok.

TIA,

Jeff.
