The reasoning behind this is that some drivers do not always process a user mode request in the context of the thread or even the process in which it was issued. Device Driver Programming In C Book Pdf Say, you have a memory stick which can display itself to the system as a new drive letter which is any available drive letter such as E:. The “Registry Path” is a string which points to the location in the registry where the information for the driver was stored. The advantage of loadable device drivers is that they can be loaded only when necessary and then unloaded, thus saving kernel memory.
