请帮忙连上int1中断

vector = HalGetInterruptVector(
ProcessorInternal,
0,
0,
1,// Vector 1 :Debug / Single Step
&Irql,
&Affinity
);
status = IoConnectInterrupt(&pkinterrupt,//OUT PKINTERRUPT
Trap_Handler,//IN PKSERVICE_ROUTINE
NULL, //IN PVOID  ServiceContext
NULL, //IN PKSPIN_LOCK
vector, //IN ULONG  Vector
                     Irql,     //IN KIRQL
Irql,     //IN KIRQL
Latched,   //IN KINTERRUPT_MODE
FALSE,      //IN BOOLEAN  ShareVector
Affinity, //IN KAFFINITY  
FALSE); //IN BOOLEAN  FloatingSave

我的这段程序总是返回 参数不正确错误
请大家帮我找找原因，谢谢
