To use the performance library, do the following:
|
||
|
|
|
||
|
|
* Define a string gszAppName that is the name of the application.
|
||
|
|
* Export the routines:
|
||
|
|
|
||
|
|
Pf_dwClientOpen
|
||
|
|
Pf_dwClientCollet
|
||
|
|
Pf_vClientClose
|
||
|
|
|
||
|
|
* In Pf_dwClientOpen, call Pf_*FixIndicies* to update the indicies
|
||
|
|
based on either a performance registry key, or fixed known values.
|
||
|
|
|
