I created a customized event,but I do not know how to set parameters with
it...
at the right now,my code is:

EventRef eventRef;
CreateEvent(NULL,kEventClassTimer,kEventTimerFire, 0,kEventAttributeNone,&eventRef);
SetEventParameter( eventRef, kEventParamAccessibleAttributeName,
typeCFStringRef, sizeof(CFStringRef), mask);

Is it wrong?
what should i do????

You're almost there:

SetEventParameter( eventRef, kEventParamAccessibleAttributeName,
typeCFStringRef, sizeof(CFStringRef), &cfString);

When handling the event:

... use string
CFRelease(cfString)

or maybe

CFRetain(cfString)
... use string
CFRelease(cfString)
