Note that registering a warning event will not trigger the event if the

monitor is already in the warning state. Applications should either

before setting the warning levels with

hm_SetMonitorWarningLevels(), or should check using

hm_GetMonitorLevel() whether the desired monitor parameter is in

range before waiting on the event returned from

hm_RegisterMonitorWarningEvent().

The phEventHandle returned by this function, is a standard Win32

auto reset event handle. However, an application should NOT close

the handle using the Win32 CloseHandle function. Instead the

application should close the handle and un-register the event using

the hm_UnregisterMonitorWarningEvent function.

Portability:

The function prototype is the same as the RAC6182. However, the

MONITOR _ID parameters are different between the platforms.

Requirements:

hm_UnregisterMonitorWarningEvent

This function cancels the Hardware Monitor registration.

BOOL hm_UnregisterMonitorWarningEvent (HANDLE

hEventHandle);

Parameters:

hEventHandle

The HANDLE that was returned by

hm_RegisterMonitorWarningEvent().

Return Values:

Returns TRUE if the monitor warning event has been successfully

unregistered; otherwise returns FALSE on failure.
