The FsRtlSetupAdvancedHeader macro is used by file systems to initialize an FSRTL_ADVANCED_FCB_HEADER structure for use with filter contexts.
AdvHdrA pointer to the FSRTL_ADVANCED_FCB_HEADER structure to be initialized.
FMutexA pointer to an initialized fast mutex that will be used to synchronize access to the FSRTL_ADVANCED_FCB_HEADER structure. The fast mutex must be allocated from nonpaged pool.
This parameter can be NULL. Callers should set this parameter to NULL if they intend to use an already existing fast mutex object. If FastMutex is NULL, the caller must explicitly set the FastMutex member of the stream context object to point to the existing fast mutex. (This can be done before or after calling FsRtlSetupAdvancedHeader.)
File systems use the FsRtlSetupAdvancedHeader macro to initialize an FSRTL_ADVANCED_FCB_HEADER structure for use with filter contexts.
When the advanced FCB header structure is no longer required, the file system must call FsRtlTeardownPerStreamContexts to free all associated per-stream context structures.
