NAME
       sesio - enclosure services device driver interface

SYNOPSIS
       #include <sys/sesio.h>

DESCRIPTION
       The  ses device driver provides the following ioctls as a means to access SCSI enclosure services devices.

IOCTLS
       The  ses driver supports the following ioctls:

       SES_IOCTL_GETSTATE    This ioctl obtains enclosure state in the	ses_ioctl structure.

       SES_IOCTL_SETSTATE    This  ioctl  is  used  to	set  parameters on the enclosure services device. The  ses_ioctl structure is used to pass
			     information into the driver.

ERRORS
       EIO	 The ses driver was unable to obtain data from the enclosure services device or the  data transfer could not be completed.

       ENOTTY	 The  ses driver does not support the requested ioctl function.

       ENXIO	 The enclosure services device does not exist.

       EFAULT	 The user specified a bad data length.

STRUCTURES
       The  ses_ioctl structure has the following fields:

	 uint32_t;		 /* Size of buffer that follows */
	 uint8_t page_code:	 /* Page to be read/written */
	 uint8_t reserved[3];	 /* Reserved; Set to 0 */
	 unit8t  buffer[1];	 /* Size arbitrary, user specifies */

EXAMPLES
       Example 1 Using the  SES_IOCTL_GETSTATE ioctl

       The following example uses the  SES_IOCTL_GETSTATE ioctl to recover 20 bytes of page 4 from a previously opened device.

	 char	abuf[30];
	 struct ses_ioctl *sesp;
	 int	status;
	 sesp = (ses_ioctl *)abuf;
	 sesp->size = 20;
	 sesp->page_code = 4;
	 status = ioctl(fd, SES_IOCTL_GETSTATE, abuf);
