Abstract:
|
|
|
|
Header file for the Performance Monitor data.
|
|
|
|
This file contains the definitions of the data structures returned
|
|
by the Configuration Registry in response to a request for
|
|
performance data. This file is used by both the Configuration
|
|
Registry and the Performance Monitor to define their interface.
|
|
The complete interface is described here, except for the name
|
|
of the node to query in the registry. It is
|
|
|
|
HKEY_PERFORMANCE_DATA.
|
|
|
|
By querying that node with a subkey of "Global" the caller will
|
|
retrieve the structures described here.
|
|
|
|
There is no need to RegOpenKey() the reserved handle HKEY_PERFORMANCE_DATA,
|
|
but the caller should RegCloseKey() the handle so that network transports
|
|
and drivers can be removed or installed (which cannot happen while
|
|
they are open for monitoring.) Remote requests must first
|
|
RegConnectRegistry().
