Notes:
|
||
|
|
|
||
|
|
All the data structures that are exposed to the mini redirector writers need to be
|
||
|
|
consolidated in this module.

// In the previous redirector implementation the file system statistics and the network
|
||
|
|
// protocol statistics were combined into one data structure ( and correctly so ) since
|
||
|
|
// the old redirector supported only one protocol. However this does not apply to the
|
||
|
|
// new redirector (RDR2) since there are more than one mini redirectors and the two
|
||
|
|
// need to be distingushed. The RDBSS_STATISTICS structure provides the file system
|
||
|
|
// level statistics while the protocol level statistics definition is under the control of
|
||
|
|
// the mini redirector implementers.
|
||
|
|
//
|
||
|
|
// The staistics can be obtained by issuing the FSCTL_RDBSS_GET_STATISTICS. If no mini
|
||
|
|
// redirector name is provided the RDBSS_STATISTICS are returned and if a mini
|
||
|
|
// redirctor name is provided the statistics of the appropriate mini redirector are
|
||
|
|
// returned ( the call is passed through to the appropriate mini redirector ).
