wdm驱动dbg输出

头文件定义输出宏

#define PTDBG_TRACE_ROUTINES            0x00000001#define PTDBG_TRACE_OPERATION_STATUS    0x00000002#define PT_DBG_PRINT( _dbgLevel, _string )          \    ( FlagOn(gTraceFlags,(_dbgLevel) ) ?            \        DbgPrint _string : ((void)0))extern ULONG gTraceFlags;

实现文件设置输出级别、调用输出

ULONG gTraceFlags = PTDBG_TRACE_ROUTINES;

PT_DBG_PRINT( PTDBG_TRACE_ROUTINES,                  ("minifilter2!NPInstanceQueryTeardown: Entered\n") );
