SESIO(7I)SESIO(7I)NAMEsesio - 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 struc‐
ture 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 func‐
tion.
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);
