device_info_t(9s)
NAME
  device_info_t - General: Is the top-level union that stores bus- and
  device-type information

SYNOPSIS
       typedef union device_info {
	   int version;
	   v1_device_info_t v1;
	   uchar_t pad[1024];
       } device_info_t;

MEMBERS
  version
      Specifies the version number of the union definition. Currently, Tru64
      UNIX supports only Version 1.

  v1  Specifies a structure that contains bus-type and device-type
      information, such as the v1_device_info_t structure.

  pad Specifies a reserved member.

DESCRIPTION
  The device_info_t union is the top-level definition of the information
  returned by the DEVGETINFO ioctl command. The first byte of the union
  stores the version number of the union definition. Currently, Version 1 is
  supported.

  The DEVGETINFO ioctl command queries the device for as much information as
  it can, initializes members of the appropriate data structures within the
  device_info_t union, then assigns the address of this union to the user's
  data buffer.
