Routine Description:

This is the initialization routine for the Cdrom file system

device driver. This routine creates the device object for the FileSystem

device and performs all other driver initialization.

Arguments:

DriverObject - Pointer to driver object created by the system.
|

|
||
Return Value:
|
||
|

NTSTATUS - The function value is the final status from the initialization
|
||
operation.
