The first thing the page fault handler will need to do is to determine the address of the page fault; you can find out this address by calling the Get_Page_Fault_Address() function (prototype in . Also, the errorCode field of theInterrupt_State data structure passed to the page fault interrupt handler contains information about the faulting access. This information is defined in the faultcode_t data type defined in. Once the fault address and fault code have been obtained, the page fault handler will need to determine an appropriate action to take
