Registering an IISR

Registering an IISR

The LoadIntChainHandler function expects three parameters that you must specify to load and register an installable ISR. The first parameter (lpFilename) specifies the filename of the ISR DLL to load. The second parameter (lpszFunctionName) identifies the name of the interrupt handler function, and the third parameter (bIRQ) defines the IRQ number for which you want to register the installable ISR. In response to hardware disconnect, a device driver can also unload an installable ISR by calling the FreeIntChainHandler function.
