Returns the type of interrupt used for a device supplying hardware interrupts.
Declaration
virtual IOReturn getInterruptType(
intsource,
int *interruptType);Parameters
- source:
The index of the interrupt source in the device.
- interruptType:
The interrupt type for the interrupt source will be stored here by
getInterruptType.kIOInterruptTypeEdgewill be returned for edge-trigggered sources.kIOInterruptTypeLevelwill be returned for level-trigggered sources.
Return Value
An IOReturn code (kIOReturnNoInterrupt is returned if the source is not valid).
