SESIO(4I) 4I SESIO(4I)

NAME


sesio - enclosure services device driver interface

SYNOPSIS


#include <sys/scsi/targets/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.

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);

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 page_size; /* Size of buffer that follows */
uint8_t page_code: /* Page to be read/written */
uint8_t reserved[3]; /* Reserved; Set to 0 */

ARCHITECTURE
