OSStatus GetInterruptFunctions (
InterruptSetID setID,
InterruptMemberNumber member,
void **refCon,
InterruptHandler *handlerFunction,
InterruptEnabler *enableFunction,
InterruptDisabler *disableFunction);
The GetInterruptFunctions function fetches interrupt control routines installed in an interrupt member. The caller passes the member set ID and the set member number in setID and member to uniquely identify the interrupt member in the tree.
Upon successful completion, GetInterruptFunctions returns the reference constant, the ISR, the IER, and the IDR to the caller.
GetInterruptFunctions may be called only from task level, not from secondary or hardware interrupt level.
