这一句如何理解?
下面是Win2k DDK中例子程序中的一个代码片断,是关于软驱驱动方面的:
VOID FdcUnload( IN PDRIVER_OBJECT DriverObject ) /*++ Routine Description: Unload the driver from the system. The paging mutex is freed before final unload. Arguments: DriverObject - a pointer to the object that represents this device driver. Return Value: none --*/ { FdcDump( FDCSHOW, (\"FdcUnload:\\n\")); // // The device object(s) should all be gone by now. // ASSERT( DriverObject->DeviceObject == NULL ); FDC_PAGE_UNINITIALIZE_DRIVER_WITH_MUTEX; //这一句不是声明不是赋值不是测试判断更不是循环,那么这是什么语句? return; } |

#define FDC_PAGE_UNINITIALIZE_DRIVER_WITH_MUTEX \\
{ \\ if ( !IsNEC_98 ) { \\ ExFreePool( PagingMutex ); \\ } \\ } 建议你装个va |
