InterruptEnabler



 
void InterruptEnabler (

                     InterruptSetMember ISTmember,

                     void * refCon);

--> ISTmember: Member set ID of the IST member requesting service.
<--> refCon: 32-bit reference constant registered with the IST member.

DESCRIPTION

Invoking InterruptEnabler reenables the interrupt member's ability to propagate interrupts to Mac OS.

Note

Apple-defined enabler functions do not use the passed values of refCon and should therefore be passed nil. The refCon value lets user-defined enabler functions receive a reference constant of the programmer's choice.
