UpdateRegistry
- checks, and if not busy, sets the "busy" key in the registry
- Reads in the text and help definitions from the .ini file
- Reads in the current contents of the HELP and COUNTER names
- Builds a sorted MULTI_SZ struct containing the new definitions
- Appends the new MULTI_SZ to the current as read from the registry
- loads the new MULTI_SZ string into the registry
- updates the keys in the driver's entry and Perflib's entry in the
registry (e.g. first, last, etc)
- deletes the DisablePerformanceCounters value if it's present in
order to re-enable the perf counter DLL
- clears the "busy" key
Arguments
lpIniFile
pathname to .ini file conatining definitions
hKeyMachine
handle to HKEY_LOCAL_MACHINE in registry on system to
update counters for.
lpDriverName
Name of device driver to load counters for
pFirstLang
pointer to first element in language structure list
pFirstSymbol
pointer to first element in symbol definition list
Return Value
TRUE if registry updated successfully
FALSE if registry not updated
(This routine will print an error message to stdout if an error
is encountered).
