IOCTL_DISK_SET_CACHE_INFORMATION IOCTL (winioctl.h)

设置磁盘配置数据。

若要执行此操作，请使用以下参数调用 DeviceIoControl 函数。

BOOL DeviceIoControl(
  (HANDLE) hDevice,                 // handle to device
  IOCTL_DISK_SET_CACHE_INFORMATION, // dwIoControlCode
  (LPVOID) lpInBuffer,              // input buffer
  (DWORD) nInBufferSize,            // size of input buffer
  NULL,                             // lpOutBuffer
  0,                                // nOutBufferSize
  (LPDWORD) lpBytesReturned,        // number of bytes returned
  (LPOVERLAPPED) lpOverlapped       // OVERLAPPED structure
);

注解

若要检索缓存信息，请使用 IOCTL_DISK_GET_CACHE_INFORMATION 控制代码。
