WebApr 2, 2010 · The next step is to populate the IRP dispatch table with function pointers to IRP handlers. In our filter driver, there is a generic pass-through IRP handler (which sends the request further). And, we will need a handler for IRP_MJ_CREATE to retrieve the names of the opening files. The implementation of the IRP handlers will be described later. WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
