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);
