POST_INIT_BUF (Compact 2013)

  • Article

3/26/2014

This structure contains information to send to the input buffer of DeviceIoControl for the post-initialization IOCTL. This is necessary for backward compatibility only; it is no longer needed.

Syntax

struct _POST_INIT_BUF {
  HANDLE p_hDevice;
  HKEY p_hDeviceKey;
} POST_INIT_BUF, *PPOST_INIT_BUF;

Members

  • p_hDeviceKey
    Open registry handle to the driver's device key.

Remarks

If a device has an Ioctl value in its registry configuration, the Device Manager invokes DeviceIoControl on the device's handle with that dwIoControlCode value after the device's initialization routine has returned. A pointer to a read-only POST_INIT_BUF containing the device's initialization information will be passed to the device in the IOCTL's lpInBuffer, and the size of the structure will be in nInBufferSize.
