RxFillAndInstallFastIoDispatch fills out a fast I/O dispatch vector to be identical with the normal dispatch I/O vector and installs it into the driver object associated with the device object passed.
A pointer to the RDBSS device object for this network redirector.
A pointer to the fast I/O dispatch table to fill in and use.
The size, in bytes, of the fast I/O dispatch table passed.
The RxFillAndInstallFastIoDispatch routine is implemented differently for monolithic and non-monolithic drivers network mini-redirector.
For non-monolithic network mini-redirector drivers, such as the Microsoft SMB redirector that links to rdbss.sys dynamically, RxFillAndInstallFastIoDispatch is a convenience routine that copies the normal dispatch I/O vector table routines to the fast I/O dispatch vector table. This routine would normally be used by a non-monolithic network mini-redirector to fill out the fast I/O dispatch table before calling RxRegisterMiniRdr. This routine uses the minimum of the FastIoDispatchSize parameter and the size of the FAST_IO_DISPATCH structure defined in ntifs.h to determine the number of bytes to copy.
For monolithic network mini-redirectors built by developers, the RxFillAndInstallFastIoDispatch routine does nothing.
