IOCTL(CTL_CODE)

IOCTL

 下图显示控制代码结果格式:

在wdm.h中定义了一系统宏来解析/反解析IO控制代码:

//宏:用来生成IOCTL 和 FSCTL功能控制代码,功能代码0-2047由微软使用,2048-4095供用户使用

#define CTL_CODE( DeviceType, Function, Method, Access ) (((DeviceType) << 16) | ((Access) << 14) | ((Function) << 2) | (Method))

//宏:提取设备类型的宏

#define DEVICE_TYPE_FROM_CTL_CODE(ctrlCode) (((ULONG)(ctrlCode & 0xffff0000)) >> 16)

//宏:提取缓存方法
#define METHOD_FROM_CTL_CODE(ctrlCode) ((ULONG)(ctrlCode & 3))

//宏:提取功能代码

#define IoGetFunctionCodeFromCtlCode( ControlCode ) (( ControlCode >> 2) & 0x00000FFF )

 

 设备类型代码:

 1 //
 2 // Define the various device type values.  Note that values used by Microsoft
 3 // Corporation are in the range 0-32767, and 32768-65535 are reserved for use
 4 // by customers.
