WebJul 6, 2010 · Here is a list of major IRP codes. I'm thinking on stuff like: Data->Iopb->TargetFileObject->ReadAccess Data->Iopb->TargetFileObject->WriteAccess But I'm not sure, I think these are available only in postoperation callback. The documentation is really cumbersome. Code sample for further clarification: WebFast I/O is specifically designed for rapid synchronous I/O operations on cached files, bypassing the file system and the storage driver stack. Therefore, in our design, we monitor both the IRPs and the fast I/O requests. A fast I/O read/write operation can be any of the types listed in Table1. phoenix health and fitness manual treadmill https://roderickconrad.com
