Object Manager Routines

Object Manager Routines

This section describes the subset of system-supplied ObXxx support routines that can be used by kernel-mode file systems and file system filter drivers. However, these routines cannot be used by device drivers.

In addition to the routines documented here, file systems and file system filter drivers can also call any of the ObXxx routines that are described in the Kernel-Mode Driver Architecture Reference and declared in Ntifs.h.
